manufacturing overhead is applied to products using the predetermined
overhead rate computed as follows:

Problem 7-17 (continued)
The traditional and activity-based cost assignments differ for two
reasons. First, the traditional system assigns all $1,980,000 of
manufacturing overhead to products. The ABC system assigns only
$1,881,000 (= $783,600 + $495,000 + $602,400) of manufacturing
overhead to products. The ABC system does not assign the $99,000 of
Other activity costs to products because they represent organization-

4. The objectivity of the interview data can be questioned because the on-
site work supervisors were undoubtedly trying to prove their case about
the cost of nonroutine jobs. Nevertheless, the activity-based costing
data certainly suggest that dramatic differences exist in the costs of
jobs. While some of the costs may be difficult to adjust in response to
Savvy competitors are likely to bid less than $2,500 per thousand
square feet on routine work and substantially more than $2,500 per
thousand square feet on nonroutine work. Consequently, Mercer
