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: Cost of food sold Wages and fringe benefits Fees paid delivery help Rent on building Monthly sales in units 5,000 8,000 10,000 $10,000 $16,000 $20,000 4,200 4,320 4,400 1,100 1,760 2,200 1,800 1,800 1,800 Depreciation on equipment Utilities 700 700 700 300 360 400 Supplies (soap, floor wax, etc.) 200 260 300 Administrative costs 1,200 1,200 1,200 Total $19,500 $26,400 $31,000 (a) Identify each cost as being variable, fixed, or mixed. Cost of food sold Wages and fringe benefits Variable Mixed Fees paid delivery help Variable 4>> Rent on building Fixed Depreciation on equipment Fixed Utilities Mixed Supplies (soap, floor wax, etc.) Mixed Administrative costs Fixed OO O (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.
