the account balance on april 1st is $60.15. on april 15th a payment of $51.00 is made. on april 25th a purchase of $91.27 is made. what is the finance charge if the annual rate is 18%? what is the new account balance?

finance charge = $
new account balance = $

Hi there!
The answer is as follows:

Finance charge = $0.14
To get this you need to take the account balance on April 1st and subtract the payment of $51.00 multiply by the annual rate of 18%, which looks like this:

$60.15 - $51.00 = $9.15 × 0.18 = 1.647
Then you divide your answer by 12 for the months of the year to get:

1.647 ÷ 12 = 0.13725
Which rounds to $0.14 for you finance charge

New balance = $100.56
To get this you take the account balance on April 1st and subtract the payment of $51.00 and then add the purchase of $91.27 and the finance charge of $0.14, like so:

$60.15 - $51.00 = $9.15 + $91.27 + $0.14 = $100.56

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
