You borrow a sum of $14,000. Your creditor charges you an interest rate of 12% nominal annual capitalized quarterly. The loan will be repaid in 7 equal annual installments. In order to have enough money at the end of each year, you decide to deposit at the end of each week an amount in an account earning a nominal interest rate of 8% capitalized semi-annually.
Calculate the amount of weekly deposits needed to accumulate enough to repay your annual payments.
