Answer:
Therefore, Marge's finance charge on the computer is $97.
Explanation:
To calculate Marge's finance charge on the computer, we need to find the total amount she will pay for the computer through the installment plan and subtract the original purchase price.
Down payment = $100
Total amount paid for the computer = Down payment + Monthly payment * Number of months
Total amount paid = $100 + ($58 * 12)
Total amount paid = $100 + $696
Total amount paid = $796
Finance charge = Total amount paid - Purchase price
Finance charge = $796 - $699
Finance charge = $97
Therefore, Marge's finance charge on the computer is $97.
