CIMA Engineering Uses a Manufacturing Costing System with One Direct

CIMA Engineering uses a manufacturing costing system with one direct cost category (direct materials) and three indirect cost categories:
a. Setup, production order, and materials-handling costs that vary with the number of batches.
b. Manufacturing operations costs that vary with machine-hours.
c. Costs of engineering changes that vary with the number of engineering changes made.
In response to competitive pressures at the end of 2016, Medical Instruments used value-engineering
techniques to reduce manufacturing costs. Actual information for 2015 and 2016 is:

The management of CIMA Engineering wants to evaluate whether value engineering has succeeded in
reducing the target manufacturing cost per unit of one of its flow controllers by 10%. Actual results for 2015 and 2016 for the flow controller are:

Required:
a. Calculate the manufacturing cost for both years.
b. Did the company achieve the target manufacturing cost per unit in 2016? Explain.
