Comparing ABC and Plantwide Overhead Cost Assignments

Wellington Chocolate Company uses activity-based costing (ABC). The controller identified two activities and their budgeted costs:

Setting up equipment $432,000
Other overhead $1,440,000
Setting up equipment is based on setup hours, and other overhead is based on oven hours.
Wellington produces two products, Fudge and Cookies. Information on each product is as follows:

Fudge Cookies
Units produced 8,000 445,000
Setup hours 6,400 1,600
Oven hours 1,600 8,000
Required:

1. Calculate the activity rate for (a) setting up equipment and (b) other overhead.

a. Setting up equipment $
per setup hour
b. Other overhead $
per oven hour
2. How much total overhead is assigned to Fudge using ABC?
$
3. What is the unit overhead assigned to Fudge using ABC? Round to the nearest cent.
$
per unit

4. Now, ignoring the ABC results, calculate the plantwide overhead rate, based on oven hours.
$
per oven hour

5. How much total overhead is assigned to Fudge using the plantwide overhead rate?
$
6a. The difference in the total overhead assigned to Fudge is different under the ABC system and non–ABC system because
