Arthur borrowed $380 for six months, with $67 monthly payments. how much interest will he pay on this loan?

Given is the borrowed amount = 380 dollars.

Repayment period = 6 months.

Monthly installments = 67 dollars.

After six months, total repaid amount would be sum of all six monthly installments i.e. 6 x 67 = 402 dollars.

The interest to be paid on this loan would be difference of total repaid amount and borrowed amount.

Interest paid = Repaid amount - Borrowed amount

Interest = 402 dollars - 380 dollars

Interest = 22 dollars.

So, he would pay 22 dollars as interest on this loan.
