Question

Alex purchased a bedroom set for $2,276 using a six-month deferred payment plan with an interest rate of 23.49%. What is the balance after the deferment period if payments of $112 are made each month?

$1,604.00

$1,884.74

$2,276.00

$2,556.74

Answer 1

Hint: use

A = P(1+r/n)^(n*t)

Answer 2

another hint: the monthly payment figure they mention has no affect on the answer (it's put in there to throw you off)

Answer 3

I know it's not $2556.74

Answer 4

or C

Answer 5

why not?

Answer 6

A = P(1+r/n)^(n*t)


A = 2276(1+0.2349/12)^(12*0.5)


A = 2556.74

Answer 7

Then I use the same formula as in the other question?

Answer 8

no you're done

Answer 9

that's the balance after 6 months

Answer 10

so you were second-guessing yourself

Answer 11

That's not the right answer

Answer 12

it says 2556.74 is wrong?

Answer 13

Yeah

Answer 14

oooh let me try this

Answer 15

oh wait nvm

Answer 16

does it say which period after the deferment period ends?

Answer 17

like "2 months after the deferment period"?

Answer 18

Nope

Answer 19

well the balance at the 6 month mark is 2556.74 if no payments are made during that 6 month window

Answer 20

let's see what happens when payments of $112 are made instead

Answer 21

What is the balance after the deferment period if payments of $112 are made each month?

Answer 22

I think it's $1884.74 because if you multipy 112 by 6 months you get that answer

Answer 23

one sec

Answer 24

ok

Answer 25

hmm not sure why, but the closest I'm getting is 1850.99, but that's nowhere near $1884.74

Answer 26

I wonder if it's implying that the interest is added after the payment is made

Answer 27

Not so sure, I'll just go with $1,884.74

Answer 28

Sakura purchased ski equipment for $1,248 using a six-month deferred payment plan. The interest rate after the introductory period is 23.79%. A down payment of $175 is required as well as a minimum monthly payment of $95. What is the balance at the beginning of the seventh month if only the minimum payment is made during the introductory period?



A. $1,112.13

B. $637.13

Do you know which this one would be? I got $637.13 but i'm not to sure

Answer 29

the down payment of 175 means only 1248-175 = 1,073 is financed

Answer 30

one sec

Answer 31

so that's the only two choices?

Answer 32

No there were two more but those were wrong

Answer 33

ok nvm that then

Answer 34

I'm guessing the interest rate for the introductory period is not given

or is it 0%?

Answer 35

Not given

Answer 36

hmm this is a tough one because you can choose not to pay during the deferment period (which I'm assuming is also the introductory period)

but I'm trying various scenarios out and I'm not getting anything close

I wish they would spell the process out clearer

is there an example from the lesson we could use?

Answer 37

if so please post it

thanks

Answer 38

No I looked through the lesson and everything was pretty crappy just like all these questions being given from this pretest

Answer 39

hmm makes me wish I could read your book/lesson alongside you

I'm ok at finance, but stuff like this is making me think otherwise lol

Answer 40

hmmm

Answer 41

would you know how to do this one?

Answer 42

Elliot is graduating from college in six months, but he will need a loan in the amount of $4,850 for his last semester. He may either receive an unsubsidized Stafford Loan with an interest rate of 6.8%, compounded monthly, or his parents may get a PLUS Loan with an interest rate of 7.8%, compounded monthly. The Stafford Loan has a grace period of six months from the time of graduation. Which loan will have a higher balance and by how much at the time of repayment?

The PLUS Loan has a higher balance by $51.84.

The Stafford Loan has a higher balance by $327.01.

The Stafford Loan has a higher balance by $148.03.

The PLUS Loan has a higher balance by $259.64.

Answer 43

I'll show you what i did first

Answer 44

Stafford Loan

F = 4850*(1 + 0.068/12)^6
= 5017.25

PLUS Loan

F = 4850*(1 + 0.078/12)^6
= 5042.25

Difference

PL - SL = 5042.25 - 5017.25 = 28

but 28 isn't in any of the options

Answer 45

F = L(1 + r/n)^nt
F = Future Value
L = Initial Loan
r = Interest Rate in Decimal Form
n = Number of Compounding Periods Per Year (intra-annual)
t = Number of Years Loaned

Answer 46

ok let me try it out

Answer 47

Stafford Loan

F = P(1+r/n)^(n*t)
= 4850*(1 + 0.068/12)^(12*12/12)
= 5,190.28


PLUS Loan

F = P(1+r/n)^(n*t)
= 4850*(1 + 0.078/12)^(12*6/12)
= 5,042.25


Difference

5,190.28 - 5,042.25 = 148.03

Answer 48

you forgot to do n*t in the exponent

you just did t in the exponent

Answer 49

oooooooh

Answer 50

also, t is in years, so 6 months = 6/12 years

1 year = 12/12 months

Answer 51

Alright, thanks so much!

Answer 52

so The Stafford Loan has a higher balance by $148.03.

Answer 53

Theres one more question I need help with, or are you annoyed of this?

Answer 54

if i don't understand it, i get a bit frustrated lol

but it's all in the learning process

Answer 55

that last one wasn't so bad since it was definitely more straight-forward

Answer 56

I wish I knew how to solve that second to last one though, which is why I wanted to see how the lesson would do it (to see an example)

Answer 57

Shanelle purchased a dining room set for $2,620 using a 12-month deferred payment plan with an interest rate of 19.49%. She did not make any payments during the deferment period. What will the total cost of the dining room set be if she must pay off the dining room set within two years after the deferment period?

$2,620.00

$3,864.00

$5,796.00

$3,178.82

Answer 58

I think this is kinda like the question we could not figure out

Answer 59

a bit but this one is more clear though, it says "She did not make any payments during the deferment period"

Answer 60

A = P(1+r/n)^(n*t)

A = 2620(1+0.1949/12)^(12*1)

A = 3178.82

note: this is NOT the answer and a lot of people think it is (which is why this trap is thrown in here). This value is used to find the final answer.

Answer 61

3178.82 is the balance after the 12 month deferment period

let's use this to find the monthly payment

Use the formula


P = L((r/n)*(1 + r/n)^(n*t))/((1 + r/n)^(n*t) - 1)


where,


P = monthly payment

L = total amount loaned or amortized

r = annual interest rate (APR)

n = number of times interest is compounded per year (compounding frequency)

t = time in years


In this case,


P = unknown (we're solving for this)

L = 3178.82

r = 0.1949 (19.49% = 19.49/100 = 0.1949)

n = 12

t = 2


P = L((r/n)*(1 + r/n)^(n*t))/((1 + r/n)^(n*t) - 1)


P = 3178.82((0.1949/12)*(1 + 0.1949/12)^(12*2))/((1 + 0.1949/12)^(12*2) - 1)


P = 160.99771204627


P = 161


So we know


Payment per period: P = $161


Number of periods: n*t = 12*2 = 24


Total Amount Paid = (Payment per period)*(Number of periods) = ($161)*(24) = $3864


Total Cost is $3864.00

Answer 62

Thank you so much! I submitted it now and the Sakura one was 637.13

Answer 63

thanks, I'll have to go back over that and think how they got that

Answer 64

oh what was the answer to "Alex purchased a bedroom set for..."

I don't think we got that either...hmm

Answer 65

It was $1,884.74

Answer 66

Ok I figured it out. Here's how it works.


The rules are that if you pay off the entire balance (this is a big IF), then NO interest will apply. So if you manage to pay off the entire balance of $2,276 within 6 months (the deferred interest period), then you will be charged NO interest at all. However, companies know very well that the majority of the people will not be able to pay off the entire balance within 6 months. So this is when they retroactively charge interest to make a lot of money.


So Alex could have made payments to fully pay off the $2,276 debt within 6 months...BUT...Alex made payments of $112 for 6 months, which means he really only paid 6*112 = 672 dollars toward the balance and he's nowhere close to paying off the entire balance of $2,276


So here's what happens


a) Alex did make 6 payments of $112 or $672 total over 6 months. So subtract this from the initial balance to get: 2,276 - 672 = 1604. Notice how the balance is not $0. So the balance was not paid for in full. If it was $0, then Alex can walk away without having to make any more payments. It's not $0, so we move onto b)


b) Because the balance was NOT paid in full by the end of the 6 month deferment period, this means that interest is applied for every month in the 6 month deferment period. All of this is applied to the initial balance and payments are not factored in (yet).



So, P*(1+r/n)^(n*t) = 2276*(1+0.2349/12)^(12*6/12) = 2,556.74


c) The balance is now 2,556.74 dollars. This would be the final answer if Alex did not make any payments at all during this 6 month period. However, alex did make monthly payments of $112 and he paid the company $672 so far. So that is subtracted from the balance to get 2,556.74 - 672 = 1,884.74


So that explains why the remaining balance after the 6 month deferment period is $1,884.74


The same basic steps are applied to the problem with Sakura as well.

Answer 67

Yeah, that's what I did

Answer 68

For the Alex one

Answer 69

ok great, glad you figured it out

Answer 70

Hey sorry to bother you but theres a question just like the Alex one
Farrah installed a new pool for $14,730 using a 12-month deferred payment plan with an interest rate of 19.33%. What is the balance after the deferment period if payments of $527 are made each month?

$14,370.00

$17,843.62

$8,046.00

$11,519.62

My brother tried to do this with me and he got $8046.00 whereas I got $11,519.62
I did exactly what you said for the Alex question like 14730(1+0.1933/12)^(12*12/12) = 17843.62
THEN I took 527*12months and got 6324
Subtracted 17843.62 - 6324 = 11519.62

I'm pretty confident with my answer but my brother is telling me I'm wrong?

Answer 71

your brother would be right if the interest wasn't applied retroactively, but it is

Answer 72

$11,519.62 is the correct answer

Answer 73

it would be nice if it was as simple as saying

initial balance - (# of months)*(payment per month)

14730-12*527

8,406

but it's not that simple and that trap is thrown in there to catch students off guard

Answer 74

Ah okay, thanks :) again!

Answer 76

Garrett is graduating from college in twelve months, but he will need a loan in the amount of $6,785 for his last two semesters. He may either receive an unsubsidized Stafford Loan with an interest rate of 6.8%, compounded monthly, or his parents may get a PLUS Loan with an interest rate of 7.8%, compounded monthly. The Stafford Loan has a grace period of six months from the time of graduation. Which loan will have a higher balance at the time of repayment and by how much?

The PLUS Loan has a higher balance by $72.54.

The PLUS Loan has a higher balance by $112.83.

The Stafford Loan has a higher balance by $177.86.

The Stafford Loan has a higher balance by $250.40


Is C the right answer?

Answer 77

Stafford Loan


A = P(1+r/n)^(n*t)


A = 6785(1+0.068/12)^(12*1.5)


A = 7511.43390604005


A = 7511.43


-------------------------------


PLUS Loan


A = P(1+r/n)^(n*t)


A = 6785(1+0.078/12)^(12*1)


A = 7333.56596333002


A = 7333.57

-------------------------------

The Stafford Loan has the higher balance


Difference:


7511.43 - 7333.57 = 177.86


So C is definitely the correct answer
