Question

For many years, Yelena Company manufactured a single product called a Mono-Relay. Then three years ago, the company automated a portion of its plant and at the same time introduced a second product called a Bi-Relay that has become increasingly popular. The Bi-Relay is a more complex product, requiring 1.00 hour of direct labor time per unit to manufacture and extensive machining in the automated portion of the plant. The Mono-Relay requires only 0.50 hour of direct labor time per unit and only a small amount of machining. Manufacturing overhead costs are currently assigned to products on the basis of direct labor-hours.

Despite the growing popularity of the company’s new Bi-Relay, profits have been declining steadily. Management is beginning to believe that there may be a problem with the company’s costing system. Materials and labor costs per unit are given below:



Management estimates that the company will incur $654,720 in manufacturing overhead costs during the current year and 18,000 units of the Mono-Relay and 7,000 units of the Bi-Relay will be produced and sold.

Required 1-a. Compute the predetermined manufacturing overhead rate assuming that the company continues to apply manufacturing overhead cost on the basis of direct labor-hours.(Round your final answer to 2 decimal places.) Predetermined manufacturing overhead rate per DLH 1-b. Using this rate and other data from the problem, determine the unit product cost of each product. (Do not round intermediate calculations. Round your final answers to 2 decimal places.) Mono-Relay Bi-Relay Unit product cost
