Strike Company produces no defective units but it wants to reduce direct materials usage per unit of Smack in year 2. Manufacturing conversion costs in each year depend on production capacity defined in terms of Smack units that can be produced. Selling and

customerservice

costs depend on the number of customers that the customer and service functions are designed to support. Neither conversion costs or

customerservice

costs are affected by changes in actual volume. Stike Company has 46 customers in year 1 and 50 customers in year 2. The industry market size for high-end golf clubs increased 5% from year 1 to year 2.
