The expansion will increase fixed costs by $270,000 but will not affect the relationship between sales and variable costs. Required: 1. Determine the total fixed costs and the total variable costs for the current year. Total variable costs Total fixed costs 2. Determine (a) the unit variable cost and (b) the unit contribution margin for the current year. Unit variable cost Unit contribution margin 3. Compute the break-even sales (units) for the current year. 4. Compute the break-even sales (units) under the proposed program for the following year. 5. Determine the amount of sales (units) that would be necessary under the proposed program to realize the $930,000 of income from operations that was earned in the current year. 6. Determine the maximum income from operations possible with the expanded plant. 7. If the proposal is accepted and sales remain at the current level, what will the income or loss from operations be for the following year?
