Each question refers to the same initial data. Treat each Part individually (unless otherwise specified). Ignore income taxes. Assume no beginning or ending inventories. Unless stated otherwise, all calculations and income statements should be based on a one- month period. Calculations and backup should be completed and submitted in Excel. Use proper Contribution Income Statement formatting - example below. Contribution Margin Format Example: Volume XX Sales XX Variable Costs (listed) XX Variable Costs Total XX Contribution Margin XX Fixed Costs (listed) Fixed Costs Total XX XX XX Operating Income Data for all questions: Holes produces chocolate glazed donuts. Their donuts are packaged by the dozen, and are sold at many grocery stores across the country. The cost of manufacturing and marketing their donuts, at their normal factory volume of 15,000 boxes per month, is shown in the table below. Holes sells their donuts for $5 per box. Holes produces their donuts in the month they are sold, and will not produce more if they do not have the customer orders (demand) for them. Holes is making a small profit, but they would prefer to increase their Operating Income. One Unit = One Box of Donuts. Hint: Fixed costs are shown on a per-unit basis in the table based on normal volume. However, fixed costs as a total do not change when volume changes, so you will need to determine total fixed costs first.
