It has been suggested that the problem lies with manufacturing overhead because it is the largest element of total manufacturing cost. Accordingly, you have been asked to find a more appropriate way of assigning manufacturing overhead cost to units of product. Required: 1. Assuming the estimated variable manufacturing overhead cost per unit is $0.40, what must be the estimated total fixed manufacturing overhead cost per quarter? 2. Assuming the assumptions about cost behavior from the first three quarters hold constant, what is the estimated unit product cost for the fourth quarter? 3. What is causing the estimated unit product cost to fluctuate from one quarter to the next? 4. Assuming the company computes one predetermined overhead rate for the year rather than computing quarterly overhead rates, calculate the unit product cost for all units produced during the year. Complete this question by entering your answers in the tabs below. Required 1 Required 2 Required 3 Required 4 Assuming the estimated variable manufacturing overhead cost per unit is $0.40, what must be the estimated total fixed manufacturing overhead cost per quarter?
