Pondside Apartments is a 900-unit apartment complex. When the apartments are 90% occupied, monthly operating costs total $224,550. When occupancy dips to 80%, monthly operating costs fall to $219,600. 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 three months. The apartment owner fears that occupancy of her apartments will drop to 65% 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 65%? Let's begin by determining the formula that is used to calculate the variable cost (slope). = Variable cost (slope) Change in cost Change in cost Change in volume Change in volume Highest cost Highest cost Highest volume Highest volume Lowest cost Lowest cost Lowest volume Lowest volume Total operating cost Total operating cost Total variable cost Total variable cost Now determine the formula that is used to calculate the fixed cost component. = Fixed cost Change in cost Change in volume Highest cost Highest volume Lowest cost Lowest volume Total operating cost Total variable cost Change in cost Change in volume Highest cost Highest volume Lowest cost Lowest volume Total operating cost Total variable cost Use the high-low method to determine Pondside's operating cost equation. y = $ x +$D Assuming the same relevant range, what should the owner expect her operating costs to be if occupancy falls to 65%? (Round your answer to the nearest whole dollar.) The owner should expect her operating costs to be $ , if occupancy falls to 65%
