If there are x $50 increases, then the revenue will be
(84-3x)(1200+50x)
Now just find the vertex of that parabola.
A company manages an apartment building with 126 units. Experience has shown that if the rent for each of the units is $1200 a month, a total of 84 units will be rented, and for each $50 increase in the monthly rent, 3 fewer units will be rented. Find the maximum revenue.
