Parkview Apartments is a 1,000-unit apartment complex. When the apartments are 90% occupied, monthly operating costs total $236,600. When occupancy dips to 80%, monthly operating costs fall to $230,200. The owner of the apartment complex is worried because many of the apartment residents work at a nearby manufacturing plant that has just announced it will close in 3 months. The apartment owner fears that occupancy of her apartments will drop to 70% if residents lose their jobs and move away. Assuming the same relevant range, what can the owner expect her operating costs to be if occupancy falls to 70%? Let's begin by determining the formula that is used to calculate the variable cost per unit (slope). Variable cost per unit (slope) Now determine the formula that is used to calculate the fixed cost component. Fixed cost Use the high-low method to determine Parkview's operating cost equation. Let x represent the number of occupied apartments. y= $x + $[ Assuming the same relevant range, what should the owner expect her operating costs to be if occupancy falls to 70%? The owner should expect her operating costs to be $, if occupancy falls to 70%
