Answer:
C. $176000 increase in operating profits
Explanation:
Contribution margin is the ability of a company to cover its variable costs using revenue. It is calculated as selling price per unit minus variable cost per unit. The amount left covers fixed costs or is profit.
Contribution margin per unit = 560 - (130 + 100 + 105 + 65) = $160
Profit increase = $160 x 1100 units = $176000
This is profit because the company already covers it’s fixed costs selling to regular customers since it had total costs of $640 per unit and sold at $960 (with a 50% mark up).
