Baker Co. expects to maintain the same inventories at the end of 2012 as at the beginning of the year. The total of all production costs for the year is therefore assumed to be equal to the cost of goods sold. With this in mind, the various department heads were asked to submit estimates of the costs for their departments during 2012. A summary report of these estimates is as follows: 1. Prepare an estimated income statement for 2012. 2. What is the expected contribution margin ratio round to the nearest whole percentage. 3. What is the expected margin of safety in dollars. Please provide calculations. I have been able to figure out the sales direct materials and direct labor but cannot figure out how the factory overhead is calculated
