Question

I can not figure this question out! Plz help!! A drill team is raising money by holding a car wash. The team earns $6.00 for each car washed. The team's expenses include $50.00 for advertising plus $0.50 in materials for each car washed. Let f(x) represent the team's total earnings for washing x cars and g(x) represents the team's total expenses for washing x cars. Describe how you can use f(x) and g(x) to obtain a function p(x) that gives the team's profit for washing x cars. Then write a rule for p(x).

Answer 1

Explanation:

Total earnings = f(x) = 6x

Total expenses =g(x) = 0.5x + 50

Profit p(x) = f(x) - g(x)

= 6x - ( 0.5x + 50)

= 6x - 0.5x - 50 = 5.5x - 50
