A sawmill cuts boards for a lumber supplier. When saws A, B, and C all work for
6 hours, they cut 7200 feet of lumber. It would take saws A and B working together 9.6
hours to cut 7200 ft of lumber. Saws B and C can cut 7200 ft of lumber in 9 hours. Find
the rate (in ft/hr) that each saw can cut lumber.
a) Write the system of equations that describes the above information.
b) Solve the system using any method.
