Unformatted text preview: Hale Scheckelhoff & Matt Millman Calculus 151 Optimizing Writing Project Two calculus students purchase 100 residential units with hopes of selling the houses with rent at $900 per month. At that price, every unit will be sold. As the rent increases (on a monthly basis by X amount of dollars) the occupancy will decrease by X/10 residential units. However, maintenance is also in the equation as an occupied unit has a maintenance cost of $100 per month while an unoccupied unit has a maintenance cost of $20 per month. The owners wish to know the amount of rent to maximize the net income from the residential units. This can be solved with a demand and cost equation. The equation for how many units are rented is: 0=(-x/10)+100 The equation for the cost of the rent for the residential units is: Y=((-x/10)+100)(900+x) These equations would work, but maintenance work is also required for each of rented and unoccupied residential units. For an occupied residential unit the cost to maintain is $100 per unoccupied residential units....
