PLEASE HELP!!!

Bob and Susie wash cars for extra money over the summer. Bob's income is determined by f(x) = 6x + 13, where x is the number of hours. Susie's income is g(x) = 4x + 18. If Bob and Susie were to combine their efforts, their income would be h(x) = f(x) + g(x). Assume Bob works 3 hours. Create the function h(x) and indicate if Bob will make more money working alone or by teaming with Susie.

Okay. So you simply have to work it out by plugging in the f(x) and g(x) into the h(x) equation. When you do that you should get:

 h(x) = 10x + 31, team with Susie
