Karen And Wayne Need To Buy A Refrigerator Because Theirs Just Broke

Karen and Wayne need to buy a refrigerator because theirs just broke. Unfortunately, their savings account is depleted, and they will need to borrow money in order to buy a new one. Sears offers them an installment loan at 15% (add-on rate). If the refrigerator at Sears costs $1,588 plus 5% sales tax, and Karen and Wayne plan to pay for the refrigerator for 3 years, what is the monthly payment? (Round your answer to the nearest cent.)

Paper For Above instruction

The task presented involves calculating the monthly payment for a refrigerator purchased via an installment loan, considering specific costs, interest rate, and repayment time frame. The calculation requires a clear understanding of how to compute total costs, interest, and installment payments using the add-on interest rate method.

Initially, we determine the total cost of the refrigerator, including sales tax. The base cost of the refrigerator is $1,588, and with a 5% sales tax, the total purchase price becomes:

\[ \text{Total Cost} = \$1,588 + (5\% \times \$1,588) = \$1,588 + \$79.40 = \$1,667.40 \]

This total represents the amount that Karen and Wayne will need to finance.

Using the add-on interest rate method, the total interest payable over the loan period is calculated as:

\[ \text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time} \]

where the principal is the total amount borrowed—which in most cases under the add-on method is the total purchase price plus interest—and the rate is expressed yearly. The loan term is 3 years.

Since the interest rate is 15% (add-on), the total interest over the 3-year period is:

\[ \text{Interest} = \$1,667.40 \times 15\% \times 3 = \$1,667.40 \times 0.15 \times 3 = \$750.33 \]

The total amount to be repaid (principal + interest) is:

\[ \text{Total Repayment} = \$1,667.40 + \$750.33 = \$2,417.73 \]

To find the monthly payment, divide the total repayment amount by the number of months over the 3-year period:

\[ \text{Number of months} = 3 \times 12 = 36 \]

\[ \text{Monthly Payment} = \frac{\$2,417.73}{36} \approx \$67.16 \]

Therefore, the monthly payment Karen and Wayne must make to pay off the refrigerator loan over three years at a 15% add-on interest rate is approximately $67.16, rounded to the nearest cent.

This calculation highlights the importance of understanding different interest calculation methods for consumer loans. The add-on rate can significantly increase the total payable amount compared to other methods such as simple interest or amortized loans. Consumers should always ensure they comprehend the terms and costs associated with any financing agreement.

In conclusion, with the total purchase price, applicable sales tax, and interest rate considered, Karen and Wayne’s monthly installment for the refrigerator amounts to about $67.16, facilitating their financial planning and loan repayment strategy within their limited resources.
