With a typical installment loan, you are asked to sign a contract stating the terms of repayment. If you pay off the loan early, you are entitled to an interest rebate. For example, if you finance $500 and are charged $90 interest (APR 8.46%), the total to be repaid is $590 with 24 monthly payments of $24.59. After 1 year, you decide to pay off the loan, so you figure that the rebate should be $45 (half of the interest for 2 years), but instead you are told the interest rebate is only $23.40. What happened? Look at the fine print on the contract. It says interest will be refunded according to the Rule of 78. The formula for the rebate is as follows: INTEREST REBATE = K(k + 1) x FINANCE CHARGE n(n + 1) where k is the number of payments remaining and n is the total number of payments. Determine the interest rebate on the following. (Round your answers to the nearest cent.) (a) $1,026 interest on an 18-month loan; pay off loan after 12 months $ (b) $330 interest on a 2-year loan with 10 payments remaining $ (c) $10,900 borrowed at 11% on a 4-year loan with 36 months remaining $ (d) $55,000 borrowed at 10% on a 5-year loan with 18 payments remaining
Unitary Method

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
