Jacarda Company makes a composting bin that is subject to wide seasonal variations in demand. Unit product costs are computed on a quarterly basis by dividing each quarters manufacturing costs (materials, labour, and overhead) by the quarters production in units. The companys estimated costs, by quarter, for the coming year are given below: Quarter First Second Third Fourth Direct materials $ 507,600 $ 253,800 $ 126,900 $ 380,700 Direct labour 253,800 126,900 63,450 190,350 Manufacturing overhead 338,400 310,200 296,100 324,300 Total manufacturing costs $ 1,099,800 $ 690,900 $ 486,450 $ 895,350 Number of units to be produced 94,000 47,000 23,500 70,500 Estimated unit product cost $ 11.70 $ 14.70 $ 20.70 $ 12.70 Management finds the variation in unit product costs to be confusing and difficult to work with. It has been suggested that the problem lies with manufacturing overhead, since it is the largest element of cost. Accordingly, you have been asked to find a more appropriate way of assigning manufacturing overhead cost to units of product. After some analysis, you have determined that the companys overhead costs are mostly fixed and therefore show little sensitivity to changes in the level of production. Required: 1. Calculate the predetermined overhead rate based on units and direct labour? (Round your "per unit" answer to 2 decimal places.) 2. Recompute the companys unit product costs in accordance with rate per unit in (1) above. (Round your answers to 2 decimal places.)
