Cost Behavior Analysis in a Restaurant: High-Low Cost Estimation Assume a Pizza Inn 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	$15,000	$24,000	$30,000
Wages and fringe benefits	4,350	4,560	4,700
Fees paid delivery help	1,300	2,080	2,600
Rent on building	1,300	1,300	1,300
Depreciation on equipment	400	400	400
Utilities	750	840	900
Supplies (soap, floor wax, etc.)	150	180	200
Administrative costs	1,500	1,500	1,500
Total	$24,750	$34,860	$41,600

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
Costs of Food Sold
Wages and fringe benefits
Fees paid delivery help
Rent on building
Depreciation on equipment
Utilities
Supplies (soap, floor wax, etc.)
Administrative costs
Total costs equation

B) Predict total costs for a monthly sales volume of 9,900 units
