Number of orders | 21 | 42 | |
Number of machine hours | 450 | 360 | |

a. Determine the unit cost for each job using a traditional
plantwide overhead rate based on direct labor hours.
Round cost per unit answers to two decimal places
when applicable.

Direct labor | ||
Overhead | ||
Total cost | ||
Units produced | ||
Cost per unit |
b. Determine the unit cost for each job using ABC. Round cost per
