Question 591787: Please help me to solve this equation: C(x)=0.4x^2-fx+m.
The cost function for the Blingo Hang gliding service is C(x)=0.4x^2-fx+m, where f represents the average fuel cost for a customer's daily excursion and m represents the monthly hanger rental. Also, C represents the monthly cost in dollars of the small business where x is the number of flight excursions facilitated in that month.
a)If $80 is estimated to be the average fuels cost (f), and the monthly hanger rental is $5000; write an equation for the cost, C, in terms of x.
My answer is cx=4/10 x^2 -80+5000
b)What is the cost when 40 flight excursions are sold in a month????
c)How many flight excursions must be sold in order to minimize the cost? Show your work algebraically.
d)What is the minimum cost?
