Question 394021: 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.
This is the equation I got out of this: P= -o.4x^ + Fx = 800
I am a little lost after that

P%28x%29+=+-.4x%5E2+%2B+f%2Ax+-+m
given:
f+=+40
m+=+800
----------
P%28x%29+=+-.4x%5E2+%2B+40x+-+800
P%28x%29+=+-+4x%5E2+%2B+400x+-+8000
P%28x%29+=+-x%5E2+%2B+100x+-+2000
I think this is the final answer
