Answer:
For Loan A, his total payback amount would be $28,638. In turn, for Loan B his total payback amount would be $35,637.60.
Step-by-step explanation:
For the 10-year Loan A, with monthly payments of $ 238.65, the total value of the payback is determined by calculating the monthly amount for the number of months that are 10 years old, that is: 238.65 x 10 x 12, the result of which is $ 28,638.
On the other hand, for the 20-year Loan B, with monthly payments of $ 148.49, the total value of the payback is determined by calculating the monthly amount for the number of months that are 20 years old, that is: 148.49 x 20 x 12, the result of which is $ 35,637.60.
(1 / 4) = .25
.25 * 100% = 25%
Uncle Bill ate 25%
Cousin Chris ate 15%
.3 * 100% = 30%
Cousin Timmy ate 30%
Little Dave ate 12%
You ate none.
Cousin Timmy ate the most, 18% of the turkey is left, and 82% of the turkey was eaten.

I converted my fractions and decimals to percents to find the different percents eaten for each person.

The number is negative, so x=-2.
The number is -2.
