Question

Bob and Susie wash cars for extra money over the summer......

Answer 1

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.

Answer 2

h(x) = 2x + 5, work alone

h(x) = 2x + 5, team with Susie

h(x) = 10x + 31, team with Susie

h(x) = 10x + 31, work alone
