Suppose billy had a zero balance on his credit card but then used the card to charge $1,900 of his tuition. his annual interest rate is 30%. complete parts a) through d) below. a) what percentage will be charged each month? he will be charged % every month. (type an integer or a decimal.)b) what will be the interest charge for the first month? he will be charged $ in interest for the first month. (round to the nearest cent as needed.)c) what is his balance after making a $100 payment? his balance after the $100 payment is $ (round to the nearest cent as needed.)d) what is the interest charge for the second month? he will be charged $ in interest for the second month. (round to the nearest cent as needed.)

Amount used from credit card = $1900

Rate of interest for 12 months = 30%

a- What percentage will be charged each month?

He will be charged % every month.

b- ) What will be the interest charge for the first month?

=  (1 month is taken as )

$47.50

He will be charged $47.50 in interest for the first month.

c) What is his balance after making a $100 payment?

Let us assume that Billy paid $100 after 1st month. So after 1st month the amount due is 1900+47.5= $1947.50

Billy paid $100 from 1947.50, so balance remains = 1947.50-100= $1847.50

d) What is the interest charge for the second month?

Now interest charge will be calculated on 1847.50

interest =

= $ 26.39 or rounding it off we get $26.40.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
