Assume that an analysis of operating costs, customer sales, and customer patronage reveals the following: $100,000/year Fixed costs per store Variable cost ratio Average sale per customer visit Average customer visits per week Customers as portion of city population Determine the city population required for a single 7-Eleven to earn an annual profit of $40,000. Round annual contribution per customer to two decimal places. For customers required for desired profit and required population, round up to the nearest whole number (i.e., 325.333 customers = 326) Annual contribution per customer Customers required for desired profit Required population 0.80 $19.00 1.50 0.05 Check $ 3,500,000 x 0x 0x
