An office building containing 96,000 square ft of spaceis to be made into apartments.There at most 15 one bedroom units,each with 800 square ft of space. The remaining units each with 1200 square ft of space,will have two bedrooms. Rent for each one bedroom is $650 and the two bedrooms are $900.How many two bedroom apts should be built to maximize revenue? 70,15,80 or 120?
I chose 70

Right!
It's interesting that the company makes more money per square foot on the onebedroom apartments than on the twobedrooms.
