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 #2 Unit sold Case 3 20,700 Case #1 9,700 $ 252,200 116,400 99,000 Caso #4 5,000 130,000 Sales $ 281,400 $ 227,700 Variable expenses Fixed expenses Net operating income (loss) Contribution margin per unit 78,000 (43,000) 161,000 (40,400) $ 99 154,400 $ $ $ b. Assume that more than one product is being sold in each of the four following case situations: Case #3 Sales Case 450,000 $ $ Case 2 197,000 130,020 Case 14 293,000 93,760 Variable expenses $ Ann Drout . Assume that more than one product is being sold in each of the four following case situations: Case 3 Case 1 $ 450,000 Case #2 $ 197,000 130,020 54,000 Case 114 $ 293,000 93,760 Variable expenses Fored expenses Net operating income (loss) Contribution margin ratio percent) $ 72,000 $ 466,000 84,630 79% $ 29.760)
