e. None of these answers is correct

A. Increase by $7,200

Explanation:

Given: Sales(10,000 units) $120,000

Less variable costs - 48,000

Contribution margin $72,000

Less fixed costs - 24,000

Net income $ 48,000

The total contribution margin is the earning of the company to cover the fixed cost of the company and generate profit.
