Somerset Corporation makes a high-end computer monitor. The company produces no defective units but it wants to reduce direct materials usage per unit in 2019. Manufacturing conversion costs in each year depend on production capacity defined in terms of 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. The industry market size for high-end computer monitors increased 5% from 2018 to 2019.
