The Lakeshore Hotels occupancy-days and custodial supplies expense over the last seven months were as follows:

Month	Occupancy-Days	Custodial Supplies Expense
March	9,600	$	15,480
April	8,800		13,890
May	12,700		18,260
June	20,500		24,200
July	28,200		30,360
August	19,600		22,130
September	15,900		19,870

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 14,800 occupancy-days? (Round the "Fixed cost" to the nearest dollar amount.)
