The Lakeshore Hotel's occupancy-days and custodial supplies expense over the last seven months were as follows. Month March April May June July August September Occupancy Days 7,200 8.000 13,500 20,500 25, 8e 18,000 15,100 Custodial Supplies Expense $ 16,700 16,150 20,150 23,350 26,000 20.750 20.000 Occupancy-days are a measure of the overall activity at the hotel. For example, when a guest stays at the hotel for three days, it is counted as three occupancy-days. Required: 1. Using least-squares regression (you may use a spreadsheet to compute the fixed and variable costs), estimate a cost formula for custodial supplies expense. (Round the "Fixed cost to the nearest dollar amount and "Variable cost" to 2 decimal places.) 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 12,200 occupancy-days? (Round the "Fixed cost" to the nearest dollar amount.) Variable cost Fixed cost Total cost $ Activate
