The problem is: A small corporation borrowed $775,000 to expand its software line. Some of the money was borrowed at 8%, some at 9%, and some at 10%. How much was borrowed at each rate if the annual interest was $67,000 and the amount borrowed was at 8% was four times the amount borrowed at 10%?
There should be three equations, and the first two are : x + y + z = 775,000 / .08x + .09y + .1z = 67,000. I am not sure what the third equation is.
