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.
