2. From the data given compute the contribution margin ratio for each of the products T and O.

6. From the data given compute variable cost per unit for each product T and O.

Prepare forecasted financial results for next year following the format of the contribution margin income statement as just shown with columns for each of the two products (assume a 32% tax rate). Also, assume that any loss before taxes yields a 32% tax savings.
8. Assume that the company expects sales of each product to increase to 64,000 units next year with no change in unit sales price. Prepare forecasted financial results for next year following the format of the contribution margin income statement shown with columns for each of the two products (assume a 32% tax rate).
