The total revenue for fred's estates llc is given as the function r(x)=200x−0.4x2, where x is the number of rooms booked. what number of rooms booked produces the maximum revenue?

250 rooms gives R(250) = 25000

Step-by-step explanation:

R(x)=200x−0.4x^2

Set derivative to zero to find min or max.

dR(x)/dx = 200 - 0.8x

200 - 0.8x = 0

x = 250

R(250) = 25000

R(249) = R(251) = 24999.6

Solution is a maximum.
