Eason Company manufactures wheel rims. The controller expects the following ABC allocation rates for 2018:

Activity Allocation Base Predetermined Overhead

Allocation Rate

Materials handling Number of parts $ 4.00 per part

Machine setup Number of setups 400.00 per setup

Insertion of parts Number of parts 26.00 per part

Finishing Number of finishing hours 90.00 per hour

Eason produces two wheel rim models: standard and deluxe. Expected data for 2018 are as follows:

Standard Deluxe

Parts per rim 4.0 7.0

Setups per 500 rims 18.0 18.0

Finishing hours per rim 1.0 5.5

Total direct hours per rim 5.0 6.0

The company expects to produce 500 units of each model during the year.

Requirements

3. Compute the estimated ABC indirect manufacturing cost per unit of each model for 2018. Carry each cost to the nearest cent.
