( 1 point) 11. A company that products and sells a single product has provided the following contribution format income statement: If the company sells 4,900 units next month, what should its new net operating income be? Show your calculations. (2 points) Suggested approach: Start with current net operating income; then compute the difference in number of units currently sold and the number of units to be sold next month [in this case, 5,0004,900=100 fewer units]; multiply this number by unit CM [have to compute unit CM by taking total CM/# of units]; if fewer units are sold, subtract from current net operating income. If more units are sold, add the amount to the current net operating income. 12. A company sells a product for $60 per unit.
