Step-by-step explanation:
The student's question is asking for the calculation of the monthly payment for a refrigerator purchase. Sam purchased a new refrigerator for $1099.99, made a $200 down payment and financed the remaining amount over a 2-year period. To calculate the monthly payment, first we find the amount that was financed: $1099.99 - $200 = $899.99. This amount will be divided over 24 months, as there are 2 years in the financing period and 12 months in a year. The monthly payment is calculated as: $899.99 / 24 = $37.50 approximately. Therefore, the correct answer is a. $37.50.
