Answer:
(a) Contribution Margin = $30 per passenger
(b) Contribution Margin Ratio = 60%
(c) Contribution Margin = $30 per passenger
Explanation:
Contribution margin is the net of sales and all the variable costs. It is the portion of sales which not used by variable costs and available for settlement of fixed cost and makes profit after that.
Contribution Margin = Selling price - variable cost
Contribution Margin = $50 - $20
Contribution Margin = $30 per passenger
Contribution margin ratio = Contribution Margin / Sales
Contribution margin ratio = $30 / $50
Contribution margin ratio = 60%
