Fill in the missing amounts in each of the eight case situations below. Each case is independent of the others. (Hint: One way to find the missing amounts would be to prepare a contribution format income statement for each case, enter the known data, and then compute the missing items.) Required: a. Assume that only one product is being sold in each of the four following case situations: Case #1 Case #2 Case #3 Case #4 9,200 20,200 4,500 $ 340,800 $ 157,500 303,600 119,600 282,800 Unit sold Sales Variable expenses Fixed expenses Net operating income (loss) Contribution margin per unit 92,000 162,000 72,000 $ 22,600 $ 56,400 $ 0 $ $ 7 b. Assume that more than one product is being sold in each of the four following case situations: Case #2 Case #3 Case #4 Case #1 449,000 Sales S $ $ 209,000 137,940 68,000 296,000 91,760 Variable expenses Fixed expenses Net operating income (loss) Contribution margin ratio (percent) 471,000 85,800 S 48,130 $ $ (11,760) 37% 80%
