WORKSHEET: ALGEBRA 3 - SOLUTION EXERCISE 9


9) A man buys a saddle, a horse, and a harness, for 360. The saddle costs twice
as much as the harness ; and the horse costs twice as much as the harness and
saddle together. What is the price of each?
x - price of the harness
2x - price of the saddle
2(x+2x) - price of the horse
x + 2x + 2(x + 2x)= 360
x + 2x + 6x = 360
9x = 360
x = 360:9
x = 40

Price of the harness - 40
Price of the saddle - 80
Price of the horse - 240
