Chapter 6.1, Problem 61PE
For Exercises 61-64, set up a system of linear equations to represent the scenario. Solve the system by using Gaussian elimination or Gauss-Jordan elimination.
Andre borrowed $20,000 to buy a truck for his business. He borrowed from his parents who charge him 2% simple interest. He borrowed from a credit union that charge 4% simple interest, and he borrowed from a bank that charge 5% simple interest. He borrowed five times as much from his parents as from the bank, and the amount of interest he paid at the end of 1 yr was $620. How much did he borrow from each source?
