Aaron has an unpaid balance of $637.24 on his credit card statement at the beginning of march. he made a payment of $25.00 during the month, and made purchases of $375.44. if the interest rate on aaron’s credit card was 12% per month on the unpaid balance, find his finance charge and the new balance on april 1.

See below in bold.

Step-by-step explanation:

His balance at the end of the month is

637.24 - 25 + 375.44 = $987.68.

So the finance charge is 987.68 * 0.12 = $118.52

and his new balance is 118.52 + 987.68 = $1106.20.

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.

maya’s expression will generate the wrong sum because she violated the commutative property.
