Colby and Danielle clean pools for extra money over the summer. Colby's income is determined by f(x) = 3x + 12, where x is the number of hours. Danielle's income is g(x) = 5x + 10. If Colby and Danielle were to combine their efforts, their income would be h(x) = f(x) + g(x). Assume Colby works 4 hours. Create the function h(x) and indicate if Colby will make more money working alone or by teaming with Danielle.

h(x) = 2x + 2, work alone
h(x) = 8x + 22, team with Danielle
h(x) = 2x + 2, team with Danielle
h(x) = 8x + 22, work alone
