A state government borrows $2,000,000 at simple annual interest. Some of the money is borrowed at 7 %, some at 8.5%, and some at 9.5%. Use a system of linear equations to determine how much (in dollars) is borrowed at each rate given that the total annual interest is $169,750 and the amount borrowed at 8.5% is four times the amount borrowed at 9.5%. Solve the system of linear equations using matrices. at 7% $ Incorrect: Your answer is incorrect. at 8.5% S Incorrect: Your answer is incorrect. at 9.5% S
