Exercise 7.25 Sunland Products manufactures two component parts: A340 and A360. AJ40 components are being introduced currently, and A160 parts have been in production for several years. For the upcoming period, 1,900 units of each product are planned for manufacturing. Assume that the only relevant overhead cost is for engineering change orders (any requested changes in product design or the manufacturing process). AJ40 components are expected to require 4 change orders and A360 only 2. Each AJ40 requires 1 machine hour, and each A360 requires 1.5 machine hours. The cost of a change order is $460. Estimate the cost of engineering change orders for A140 and A360 components if Sunland uses a traditional costing method and machine hours as the allocation base. (Round machine hour rate to 2 decimal places, e.g. 25.69 and final answers to O decimal places, e.g. 5,275.) Total allocated cost for AJ40 $ Total allocated cost for AJ60 $ Now suppose that Sunland uses an ABC system and allocates the cost of change orders by using as cost driver the number of change orders. Estimate the cost for change orders for each unit of AJ40 and AJ60 Total allocated cost for AJ40 Total allocated cost for AJ60 Calculate the difference in overhead allocated to each product. (Round answers to o decimal places, e.g. 5,275. Show an undercharge preceded by a minus sign, e.g. -256 or (256).) Overcharge (Undercharge) for A340 s Overcharge (Undercharge) for A360 s
