Frankie’s car broke down. The repair costs are $400. Because he does not have any money saved, he will have to get a "payday loa
n" for the car repair. He researched 7-day payday loans and found that he will owe $9.50 for every $100 he borrows, plus the money he borrows. How much will Frankie have to pay back, if he takes the 7-day payday loan?$38.00$438.00$509.50$766.50
