Guest-days is a measure of the overall activity at the hotel. For example, a guest who stays at the hotel for three days is counted as three guest-days.
Requirement 1: Using the high-low method, estimate a cost formula for custodial supplies expense where X is the number of guest-days.
Requirement 2: Using the cost formula you derived above, what amount of custodial supplies expense would you expect to be incurred at an occupancy level of 4,590 guest-days?
