Barbara got a flat tire and does not have a spare. She needs her car for work, so she goes to a business that offers payday loans in order to get the money to buy a new tire. She borrows 75 dollars and plans to pay it back when she gets paid in 8 days. Barbara is charged a fee of 15 dollars and the term on her loan is 8 days. Approximately what is the annual percentage rate on her loan?
