The Lakeshore Hotel's occupancy-days and custodial supplies expense over the last seven months were as follows: Occupancy- Custodial Supplies Month Days Expense March 18,100 $14,800 April 12,580 15,290 May 15,120 22,210 June 28,800 27,850 July August 24,600 31,540 17,200 23,530 September 14,700 21,980 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 the high-low method, 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= 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 13,400 occupancy-days? (In your computations, round "Variable cost per unit" to 2 decimal places and final answers to the nearest dollar amount.) Variable cost Fixed cost Total cost Amount
