When Harsh graduated from school, he had a $22,000 OSAP loan. The interest charged on the loan is approximately 4.5% compounded monthly. Harsh decided that he would better focus on getting the loan paid off as soon as possible to save on paying too much extra interest. He set for himself the goal of repaying the loan in three years.

How much should Harsh's monthly loan payments be to reach his goal?

What will be the total interest paid?
