Both product lines appear profitable. Using ABC we see that Model
145 is not generating nearly as much profit as it appeared to generate
using the volume-based systems in Exercise 17-7 and Exercise 17-8.

1. Total direct labor hours:
Product A: 10,000 units x 0.20 DLH/unit = 2,000 DLH
Plant-wide overhead rate:
$249,000/2,500 DLH = $99.60/DLH

A: 10,000 units x $2/unit $ 20,000
B: 2,000 units x $3/unit $ 6,000
Direct labor

Using this approach (activity based costing) the company sees that
Product B is not profitable, and Product A is profitable. The company
should evaluate the activities used to produce Product B and
