She developed an ABC system very similar to the one used by Dettling's chief rival. Part of the reason Metzgar developed the ABC system was because Dettling's profits had been declining even though the company had shifted its product mix toward the product that had appeared most profitable under the old system.

(Enter amounts to two decimal places.) Begin by computing the total manufacturing cost per wheel for each wheel model. Requirements 1. Compute the gross profit per wheel if managers rely on the ABC unit cost data. 2. Compute the gross profit per wheel if the managers rely on the plantwide allocation cost data. 3. Which product line is more profitable for the company? 4. Why might the controller have expected ABC to pass the cost-benefit test? Were there any warning signs that the company's old direct-labor-based allocation system was broken
