Jacarda Company makes a composting bin that is subject to wide seasonal var a quarterly basis by dividing each quarter's manufacturing costs (materials, labour, and overhead) by the quarter's production in units. The company's estimated costs, by quarter, for the coming year are given below: Quarter Direct materials Direct labour Manufacturing overhead Total manufacturing costs Number of units to be produced Estimated unit product cost First Second Third $436,800 $218,400 $109,200 $327,600 218,400 109,200 54,600 163,800 280,800 296,400 265,200 249,600 $951,600 $592,800 $413,400 $772,200 104,000 52,000 26,000 78,000 9.90 9.15 $ 11.40 $ 15.90 $ Fourth 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 company's 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.)
