a.1Assume the St. Falls plant uses a single plantwide overhead rate to assign all overhead (plantwide and department) costs to jobs. Find the overhead rate by using expected direct labor hours.
a.2Determine the projected amount of total manufacturing costs per unit for the units in job no. 110.
b.1Calculate plantwide overhead rate using Machine Hours on projected manufacturing costs for job no. 110.
Plantwide overhead rate $ per machine hour
b.2Calculate two separate department overhead rates using Machine Hours on projected manufacturing costs for job no. 110.
b.3Recalculate the projected manufacturing costs for job no. 110 using three separate rates: one rate for plantwide overhead and two separate department overhead rates, all based on machine-hours.
