Match the letters with the matching number.
1)$42 over 2 years at an interest rate of 3%
2)$40 over 4 years at an interest rate of 2%
3)$48 over 2 years at an interest rate of 4%
4)$40 over 2 years at an interest rate of 5%
A)p=$500
B)p=$600
C)p=$700

Answer 1

good thing i aint getting a grade on it

Answer 2

lol

Answer 3

but i am

Answer 4

what type of interest? simple, compounded, continuous?

Answer 5

simple

Answer 6

well then, percents are a measure of 100 parts; so we have to divide our number by 100. for example:

42/100 = 1% of 42 ; but we want 3 of them

42(3)/100 = 3%, simple interest for 1 year

Answer 7

i dont see how the answers are the interest; unless there is some other part of the instructions that you are just not telling

Answer 8

Match the information about interest earned with the principal amount invested. Remember the equation for calculating simple interest is .

Answer 9

ooooo .... so your given interest and match it to prinipal

Answer 10

I=prt

Answer 11

yea

Answer 12

so what parts got you stumped?

Answer 13

sorry i left that out its very important

Answer 14

all of it

Answer 15

well, the problem suggests that youve already been taught "most" of it at least

Answer 16

and i dont really have the time to reinvent the wheel on it

Answer 17

If we know the formula; we just fill in the parts to find whats missing

Answer 18

I = p r t for

$42(I) over 2(t) years at an interest rate of 3% (r)

42 = p .03 2

42
----- = p
2*.03

Answer 19

the formula is I=prt but i get confused

Answer 20

rearrange it to fit better; solve it for "p"

I/(rt) = p

Answer 21

oh ok thanks so can you match the letters and numbers together please.

Answer 22

i could yes, but id rather dbl chk your efforts; that way i dont feel like im just being used for cheap labor.

You show me yours and all show you mine :)

Answer 23

oh ok

Answer 24

Answer 29

2) A
3)B
4)D

Answer 30

fair enough :)

1)$42 over 2 years at an interest rate of 3%

42/(2*.03) = 700

2)$40 over 4 years at an interest rate of 2%

40/(4*.02) = 500

3)$48 over 2 years at an interest rate of 4%

48/(2*.04) = 600

4)$40 over 2 years at an interest rate of 5%

40/(2*.05) = 400

Answer 31

i believe we agree

Answer 32

yea thanks for the help!

Answer 33

good luck :)

Answer 34

thank you
