Assume that the value-stream costs and total units shipped apply only to one model (a single-product value stream). Calculate the unit cost. Round your answers to two decimal places. 56.25 per unit Complete the statement below on the accuracy of the value computed. The cost is very accurate as the value stream costs all belong to that product 2. Assume that Tool SK1 is responsible for 60% of the materials cost. Calculate the unit cost for Tool SK1 and Tool SK3. Explain the rationale for using units shipped instead of units produced in the calculation. Round your answers to two decimal places. Tool SK1 Tool SK3 Complete the statement below on the accuracy of the Model A and Model B values computed. Complete the statement below that explains the rationale for using units shipped instead of units produced in the calculation. Using units shipped for the unit calculation motivates managers to reduce inventories. 3. Calculate the unit cost for the two models, using DBC. Round your answers to two decimal places. SK1 SK3 S
