Answer:
Part 1) Her total payback amount is $8,389.20
Part 2) $889.20
Step-by-step explanation:
Part 1) What is her total payback amount
we know that
To find out the payback amount, multiply the monthly payment by the number of months
Remember that
5 years is equal to 5(12)=60 months
so
[tex]\$139.82(60)=\$8,389.20[/tex]
therefore
Her total payback amount is $8,389.20
Part 2) How much interest will she pay on this loan?
Subtract the amount of the loan from the total payback amount
so
[tex]\$8,389.20-\$7,500=\$889.20[/tex]
