Set up a system of linear equations to represent the scenario. Solve the system by using Gaussian elimination or Gauss-Jordan elimination. Assume the interest rates are annual. Karen borrowed S$25,000 to buy a truck for her business. She borrowed from her parents who charge her 4% simple interest. She borrowed from a credit union that charges 7% simple interest, and she borrowed from a bank that charges 2% simple interest. She borrowed five times as much from her parents as from the bank, and the amount of interest she paid at the end of 1 yr was $1150. How much did she borrow from each source? Karen borrowed S from her parents, $Į from the credit union, and S from the bank.
