help

Answer 1

how do we do time @az

Answer 2

number 5

Answer 3

what are you doing?

Answer 4

number 5 the time

Answer 5

Same concept as #3 except that we know the rate but now we're solving for time

A = P * (1 + rt)

Can you tell me what the A, P and r are going to be for #5?

Answer 6

there aren't any numbers
plus, the fifth line-ish thing/paragraph thing
is like addition
??

Answer 7

wrong ss

Answer 8

lol

Answer 9

yeah I assumed as much haha. This is the question:

Answer 10

interest stuff----
umm
should i assume the first line is the principle, the second is interest is it annual or what? and the third is time, and the fourth is the ending sum-ish thing

Answer 11

first is the principle
second is the annual rate
third is time
fourth is the interest

Answer 12

I have to do time

Answer 13

remember the A in our equation is the initial amount + interest

the initial amount is in the first column and the interest is in the last column

so what is 4800 + 2160

Answer 14

6960

Answer 15

So that's your A

what is your rate (convert it to a decimal)
and what was the initial amount again?

Answer 16

6.960

Answer 17

no no

6960 is our A

A = P * (1 + rt)

what is our RATE (9%) as a decimal?
and what is our P the principle our the initial amount? It's the number in the first column

Answer 18

0.09

Answer 19

@az

Answer 20

and what was the beginning amount?

Answer 21

4800

Answer 22

good so now we have

A = 6960
P = 4800
r = 0.09

so put it all into our formula

6960 = 4800 * (1 + (0.09t))

we have to solve for t

can you do that?

Answer 23

divide

Answer 24

yes divide by 4800 on both sides

Answer 25

I got 53 repeated

Answer 26

what did you divide
6960 = 4800 * (1 + (0.09t))

we should first be doing

6960 / 4800 =

Answer 27

1.45

Answer 28

@az

Answer 29

so now we have

1.45 = 1 + 0.09t

subtract 1 on both sides

and then divide by 0.09

Answer 30

I got .0405

Answer 31

@az

Answer 32

1.45 - 1 =

are you sure it's 0.0405

Answer 33

I got .45 and you said times it by 0.09

Answer 34

so I did

Answer 35

DIVIDE

Answer 36

5 I'm sorry calm down

Answer 37

because we'll have

0.45 = 0.09 * t

since we're multiplying 0.09 and t,
to get t all by itself
we have to divide on both sides

Answer 38

Oh I'm sorry, I'm not yelling. I'm just using caps to show emphasis on the word haha

Answer 40

yes :)

now just divide

0.45/0.09 =

Answer 41
