That was the key word.
It doesn't have to increase.
Breakeven point would move higher.
Depends actually, but since there's very little information in the question you can pretty much twist your answer in different directions.
If you had to recommend one way to decrease the company's sales at breakeven point what will be your choice?
This means that you want to reach breakeven point with less sales, right?
Possibilities:
=> you decrease your fixed cost. But I assume that's not possible since the situation started with an increase to begin with.
=> you can substantially decrease your variable costs. No way of knowing that that is possible, considering the lack of information in the question.
=> you increase the product price. Always an easy & correct solution, but not always a realistic one, but again a lack of information.
