if jennifer pays off the couch in one year, she will have to pay no interest. If she pays off her balance in 12 equal monthly installments, how much will she pay each month?
You forgot to post the amount of her balance.
That depends upon how much she spent.
Some stores require you to pay monthly interest on "no interest for one year" promotions, and then refund the interest at the end of a year if the debt is paid off.
Assuming there is not interest to pay, ever, divide the cost by 12 for the monthly payment.
To calculate the monthly payment, we need two pieces of information: the total cost of the couch and the number of months she will be paying off the balance.
Let's assume the total cost of the couch is $C. Since Jennifer will be paying off the couch in 12 equal monthly installments, she will pay the same amount each month.
If she pays off the entire balance in one year (12 months) with no interest, then the monthly payment would be the total cost divided by the number of months:
Monthly payment = Total cost / Number of months
Thus, Jennifer's monthly payment would be:
Monthly payment = C / 12
Please note that this calculation assumes there are no additional fees, taxes, or other charges associated with the purchase of the couch.
