the principal of your school is buying 3 computers at $900 each. She can pay $98 per month instead of paying the full price. Will she have paid for them by the end of 12 months?
The total cost of the 3 computers is $900*3 = $2700.
If the principal pays $98 per month for each computer, she will be paying $98*3 = $294 per month.
It won't take her 12 months to pay because $294*12 = $3528.
If we round up $294 to $300 --> $2700 / $ 300 per month = 9 months. However, this is an overestimation, so she will need 10 months to pay.
