The total revenue for Fred's Estates LLC is given as the function R(x)=200x−0.25x2R(x)=200x−0.25x2, where x is the number of rooms rented. What number of rooms rented produces the maximum revenue?

Hello, and welcome to FMH!

We like for students to show what they've done so we can offer the best help.

I assume you mean:

$$\displaystyle R(x)=200x-0.25x^2$$

Are you expected to use marginal revenue to answer this question?

I believe so. We have to answer how many rooms it is.

Okay, have you computed the marginal revenue function?
