Answer:
Break-even point
Step-by-step explanation:
The Break-even point is the level of sales where the revenue realized matches the costs incurred. At the break-even point, the business does not make any profits or losses.
Helen has reached the break-even point. By selling 25 cups of lemonade, her revenue equals the total of her fixed and variable costs. A sale of 25 cups does not generate any profits or losses.
