5) The profit function for the Recklus Hang gliding Service is P(x) = -0.4x2 + fx - m, where f represents the set up fee for a customer’s daily excursion and m represents the monthly hanger rental. Also, P represents the monthly profit in dollars of the small business where x is the number of flight excursions facilitated in that month.
a) If $40 is charged for a set up fee, and the monthly hanger rental is $800; write an equation for the profit, P, in terms of x.
Typing hint: Type x-squared as x^2

Hi
P(x) = -0.4x^2 + fx - m where f is set up fee, m the hanger charge
& x is # of flights excursions facilitated in that month
a) If $40 is charged for a set up fee, and the monthly hanger rental is $800
P(x) = -0.4x^2 + $40x - $800
b) How much is the profit when 30 flight excursions are sold in a month
P(30) = -0.4(30)^2 + $40(30) - $800 = $40

Answer: P(x) = -0.4x^2 + 40x - 800
============================================
b) How much is the profit when 30 flight excursions are sold in a month?
Answer: P(30) = -0.4(30^2) + 40*30 - 800
P(30) = -360 + 1200 - 800
---
P(30) = $40
