2 The Lakeshore Hotel's occupancy-days and custodial supplies expense over the last seven months were as follows: Custodial Supplies 10 Occupancy- Month points Days Expense March 9,300 $ 19,180 April 8,700 17,870 May 12,800 21,580 June 20,500 25,900 Print July August 27,900 30,340 19,400 23,890 September 15,800 22,430 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.) Y = EX 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 14,600 occupancy-days? (Round the "Fixed cost" to the nearest dollar amount.) Variable cost Fixed cost Total cost
