Final answer:
To calculate the finance charge, subtract the down payment from the total price of the refrigerator. Then, calculate the monthly interest rate using the APR. Finally, multiply the monthly interest rate by the amount financed to find the finance charge. The finance charge is $11.89488.
Step-by-step explanation:
To calculate the finance charge, we first need to calculate the amount financed. The refrigerator sells for $989.99 and Harry makes a 20% down payment, which is 0.20 * $989.99 = $197.998. The amount financed is the remaining amount, which is $989.99 - $197.998 = $792.992.
Next, we need to calculate the interest on the loan. The APR is 18% and the loan has 12 monthly payments, so the monthly interest rate is 18% / 12 = 1.5%. The interest on the loan is 1.5% * $792.992 = $11.89488.
Therefore, the finance charge is $11.89488.
