Answer:
The answer Is 6 months. At the end of 6 months, she still owes $720 for the refrigerator.
Step-by-step explanation:
If your paying $80 per month for a fridge that costs $1200 it will take 15 months to pay for it. If you have $720 left to pay you divide that by $80(payment rate per month)which gives you 9 (months) and that is how many months you have left to pay for it, But you're looking for how many months you have already payed for it so you would subtract 9 from 15 and that gives you 6, which is the number of months you have already payed for it.
