Question 743383
Let c = computer's cost = 1650
Interest = Percentage x Amount owed / number of payments
So I = 7/100 x 1490 / 12
7/100 is the percentage
1490 is the amount owed which is the cost minus the down payment
and because he pays once a month for a year he is making 12 payments
so I = 10430 / 1200
Now rounded to nearest cent
so it's 8.69$
