Final answer:
Marie will need to make payments for 7 months to pay off her remaining phone debt of $385.95, with the final payment being less than $60.
Step-by-step explanation:
The question asks how many more months Marie will need to make payments of $60 per month to pay off her remaining $385.95 phone debt assuming no interest is involved. To find the number of months required, you divide the total debt by the monthly payment. Thus, $385.95 ÷ $60 ≈ 6.43.
Since you cannot have a fraction of a month as a payment, Marie will need to make 6 full payments, and the seventh payment will be less than $60 to cover the remaining balance.
