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) 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.

	Fixed Costs	Variable Costs
Cost of food sold	Answer	Answer	X
Wages and fringe benefits	Answer	Answer	X
Fees paid delivery help	Answer	Answer	X

Utilities	Answer	Answer	X
Supplies (soap, floor wax, etc.)	Answer	Answer	X
Administrative costs	Answer	Answer	X
Total costs equation	Answer	Answer	X

(B) Predict total costs for a monthly sales volume of 9,100 units.
