Simple Interest Simple interest is the amount of money the borrower pays based on the amount borrowed (the principal) for a given period of time (months or years). It is calculated this way: I = prt. If a person borrows $20,000 (p) to buy a car,
pays 6.95% interest (r), and takes 5 years (t) to repay the loan, how much will the borrower pay in simple interest?_
