Problem 4 Solve each of the following parts. Part 1: (2 points) (Exercise 5.27) A borrower is repaying a loan with payments of $2000 at the end of every year over an unknown period of time. If the amount of interest in the 4th installment is $1500, find the amount of principal in the 6th installment. Assume that interest is 9% convertible quarterly. ANSWER =$ Part 2: (2 points) (Exercise 5.32) A has money invested at effective rate i. At the end of the first year A withdraws 118% of the interest earned, at the end of the second year A withdraws 236% of the interest earned, and so forth with the withdrawal factor increasing in arithmetic progression. At the end of 13 years the fund is exactly exhausted. Find i. i = %. Part 3: (2 points) (Exercise 5.29) A loan is repaid with payments which start at $200 the first year and increase by $50 per year until a payment of $1050 is made, at which time payments cease. If interest is 3% effective, find the amount of principal in the 4th payment. ANSWER =$ Problem 4 Solve each of the following parts.
