Management is considering a plant expansion program for the following year that will permit an increase of $13,090,000 in yearly sales. The expansion will increase fixed costs by $4,000,000 but will not affect the relationship between sales and variable costs.

Required:

1. Determine the total variable costs and the total fixed costs for the current year.

Total variable costs	$fill in the blank 1
Total fixed costs	$fill in the blank 2

2. Determine (a) the unit variable cost and (b) the unit contribution margin for the current year.

Unit variable cost	$fill in the blank 3
Unit contribution margin	$fill in the blank 4

3. Compute the break-even sales (units) for the current year. fill in the blank 5 units

4. Compute the break-even sales (units) under the proposed program for the following year. fill in the blank 6 units

5. Determine the amount of sales (units) that would be necessary under the proposed program to realize the $60,400,000 of operating income that was earned in the current year. fill in the blank 7 units
