Fred's weekly earnings for mowing lawns can be represented by the function f(x) = 45x - 40, and george's weekly earning for delivering papers can be represented by the function g(x) = 85x - 110. fred says that after 3 weeks they will have earned the same amount. determine whether fred is correct. explain.
