Giving the following information:

Selling price = $133.6

Total variable cost (4,000 units) = $383,600

Unitary variable cost = 383,600/4,000 = $95.9

Total variable cost (5,000 units) = 479,500

Unitary variable cost = 479,500/5,000 = $95.9

The contribution margin is calculated using the following formula:

Contribution margin = sales - total variable cost

Contribution margin = 4,300*133.6 - 4,300*95.9

Contribution margin = $162,110
