Marine, incorporated, manufactures a product that is awailable in both a flexdble and a rigid model. The compary has made the rigid model for years; the flexlble model was introduced several years ago to tap a new segment of the maricet. Since introduction of the flexible model, the company's profits have steadily declined, and management has become concerned about the accuracy of its costing system.

The flexible model requires 2.5 hours of direct labor time per unit, and the regular model requires 1.25 hours. Direct materials and labor costs per unit are given below. Required: 1-a. Compute the predetermined overhead rate using direct labor-hours as the basis for allacating overhead costs to products. 1.b. Compute the unit product cost for one unit of each model. 2. An intern suggested that the company use activity based costing to cost its products. A team was formed to imvestigate this idea. It came back with the recommendation that four activity cost pools be used. These cost pools and their associated activities are listed as follows: Compute the activity rate for each of the activity cost pools. 3-a. Using activity based costing. determine the total amount of overhead that would be assigned to cach model for the year. 3.b. Using activity-based costing, compute the unit peoduct cost for one unit of each model. Complete this question by entering your answers in the tabs below.
