Manufacturing conversion costs in each year depend on production capacity defined in terms of SPX 1000 units that can be produced. Selling and customer-service costs depend on the number of customers that the customer and service functions are designed to support. Neither conversion costs or customer-service costs are affected by changes in actual volume. Calculate Inc. has 23 customers in year 1 and 25 customers in year 2. The industry market size for hand held calculators increased 5% from year 1 to year 2. Of the $6 increase in unit selling price, $2 is due to a general increase in prices. Required
