1- (1 + 0.12/12) -12(30) xponent. i am trying to simplify this and i do not understand? this is how to find the monthly payment of:

consider a student loan of $25,000 at a fixed apr of 12% for 30 years.
a. calculate the monthly payment.
b. determine the total amount paid over the term of the loan.
c. of the total amount paid, what percentage is paid toward the principal and what percentage is paid for

what the question so we can you out

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
