Sunland Inc. is a manufacturer of quality shoes. The company has always used a plant-wide allocation rate for allocating manufacturing overhead to its products. The plant manager believes it is time to change to a better method of cost allocation. The accounting department has established the following relationships between production activities and manufacturing overhead costs: Activities Cost Drivers Allocation Rate Material handling Number of parts $8.00 per part Assembly Labour hours 80.00 per hour Inspection Time spent by item at inspection station 19.00 per minute The previous plant-wide allocation rate method was based on direct manufacturing labour hours, and if that method is used, the allocation rate is $800 per labour hour.

What are the indirect manufacturing costs per pair of shoes to produce a batch of 1,000 pairs, assuming the previous plant-wide allocation rate method is used
