Shirrell Blackthorn is the accountant for several pizza restaurants based in a tr-city area. The president of the chain wanted some help with budgeting and cost control, so Shield decided to analyze the accounts for the past year. She divided the accounts into four different categories, depending on whether they appeared to be primarily fixed or to vary with one of three different drivers. Food and wage costs appeared to vary with the total sales dollars. Delivery costs varied with the number of miles driven (workers were required to use their own cars and were reimbursed for miles driven). A group of other costs, including purchasing, materials handling, and purchases of kitchen equipment, dishes, and pans, appeared to vary with the number of different product types (0.9. pura, salad, and lasagna). Shirrell came up with the following monthly averages Food and wage costs $ 179,550 Delivery costs $ 17,400 Other costs $ 154 Fixed costs $ 230,000 Sales revenue 580,000 Delivery mileage in miles 6,000 Number of product types s Required 1.
