Answer:
The total amount of interest paid on all three loans is 8,748.
Explanation:
Each person has borrowed 5,000 for the same period and with the same interest rate. However, the repayment is made differently by each person.
We calculate the interest paid by each person, and then sum up the three interest payments.
Seth pays = [5000 x (1 + 0.12/2)^10] - 5000 = 3,954
Janice pays = 5,000 X 0.06 x 10 = 3,000
Lori pays = [(5,000 x 10) / 7.36] - 5,000 = 1,794
Total interest payment = 3,954 + 3,000 + 1,794 = 8,748
