Answer:
contributes towards paying fixed costs and increasing profits.
Step-by-step explanation:
the contribution margin ratio = (sales revenue - variable costs) / sales revenue
The contribution margin ratio measures how much does every extra unit sold contributes to pay for fixed costs and increase profits. Once the break even point is reached, every extra dollar sold increases profits in the proportion of the contribution margin ratio, e.g. contribution margin ratio is 35%, every extra dollar generates 35 cents in profits.
