a complex has 205 apartment units. When the rent is $635 per month all 205 units are occupied.Assume that for each $75 increase in rent 15 units becomes vacent. Assume that the number of occupied units is a linear function of the rent. Each occupied unit also requires an average of $60 per month for sevice charges. The rent charge should maximize the profits. Obtain a formula to show the profit.
