Bayside Apartments is a 750-unit apartment complex. When the apartments are 90% occupied, monthly operating costs total $217,175. When occupancy dips to 80%, monthly operating costs fall to $212,600. 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%?
