Cost Behavior Analysis in a Restaurant: High-Low Cost Estimation Assume a Papa John's restaurant has the following information available regarding costs at representative levels of monthly sales:

	Monthly sales in units
	5,000	8,000	10,000
Cost of food sold	$10,000	$16,000	$20,000
Wages and fringe benefits	4,200	4,320	4,400
Fees paid delivery help	1,200	1,920	2,400
Rent on building	1,300	1,300	1,300
Depreciation on equipment	500	500	500
Utilities	800	920	1,000
Supplies (soap, floor wax, etc.)	200	260	300
Administrative costs	1,600	1,600	1,600
Total	$19,800	$26,820	$31,500

(a) Identify each cost as being variable, fixed, or mixed.

Cost of food sold	Variable Fixed or Mixed?
Wages and fringe benefits	Variable Fixed or Mixed?
Fees paid delivery help	Variable Fixed or Mixed?
Rent on building	Variable Fixed or Mixed?
Depreciation on equipment	Variable Fixed or Mixed?
Utilities	Variable Fixed or Mixed?
Supplies (soap, floor wax, etc.)	Variable Fixed or Mixed?
Administrative costs	Variable Fixed or Mixed?

(b) Use the high-low method to develop a schedule identifying the amount of each cost that is fixed per month or variable per unit. Total the amounts under each category to develop an equation for total monthly costs.

Round variable cost answers to two decimal places.
