James has decided to start saving for a cruise over the summer. His money is currently in the local bank, modeled by the function s (x) = 102. He is able to do work around the neighborhood to earn extra money and that function would be a (x) = 8 (x + 2), where x is measured in hours. Explain to James how he can create a function that combines the two, and describe any simplification that can be done.

Danna Weber · Answer 1

S (x) = 102, a (x) = 8 (x + 2)

A function that combines the two:

f (x) = s (x) + a (x) = 102 + 8 (x + 2) =

= 102 + 8 x + 16

f (x) = 8 x + 118
