In this case for the maximum number of one-bedroom apartment, we have:
[tex]96000-(15\cdot800)=84000[/tex]
84000 square feet for two-bedrooms apartments, so:
[tex]\frac{84000}{1200}=70[/tex]
70 two-bedrooms apartment, and in this case the revenue is:
[tex]15\cdot650+70\cdot900=72750[/tex]
And the revenue becomes smaller for fewer one-bedrooms apartments, so in this case tto maximize the revenue 70 two-bedrooms apartments should be built.
