Tamara has decided to start saving for spending money for her first year of college. Her money is currently in a large suitcase under her bed, modeled by the function s (x) = 450. She is able to babysit to earn extra money and that function would be a (x) = 6 (x - 2), where x is measured in hours. Explain to Tamara how she can create a function that combines the two, and describe any simplification that can be done.

The combines is just added these two up. Because the first function is a constant, there is no independent variable. After combination, t (x) = 6 (x-2) + 450. Then open the bracket, t (x) = 6x+438.
