Question

Adam earns a base pay plus a commission for each car he sells at Crazy Carl's Cool Cars. His monthly salary is modeled by the function f(c) = 250c + 500. If Adam doesn't sell a car, how much money does he earn for the month?

Answer 1

c = numbers of cars he sold

If he does not sell any cars, then c = 0.

f(c) = 250c + 500

f(0) = 250 * 0 + 500

f(0) = 0 + 500

f(0) = 500

If he doesn't sell any cars in a month, he earns $500 in that month.
