Chapter 2.2, Problem 43E

Apartment rental The owner of an apartment building can rent all $50$ apartments if she charges $\$1800$ per month, but she rents one fewer apartment for each $\$60$ increase in monthly rent.

Construct a table that gives the revenue generated if she charges $\$1800$, $\$1860$, and $\$1920$.

Does her revenue from the rental of the apartments increase or decrease as she increase the rent from $\$1800$ to $\$1920$?

Write an equation that gives the revenue from rental of the apartments if she marks $x$ increases of $\$60$ in the rent.

Find the rent she should charge to maximize her revenue.
