Answer:
Break-even point in units would not change.
Step-by-step explanation:
Given:
Selling price = $30 per unit.
Variable cost = $18 per unit.
Fixed cost = $720,000.
New variable cost = $15.
New fixed cost = $900,000.
And, the selling price remains same, it doesn't change.
Now, to find the break-even point in units would be.
Now, to find the Current break-even point by using formula:
![Current\ breakeven\ point=(Fixed\ cost)/(selling\ price\ -\ variable\ cost)](https://img.qammunity.org/2021/formulas/business/college/oyiri5r6hm38u34cdktkzdj90gvx7vvteq.png)
![Current\ breakeven\ point=(720,000)/(30\ -\ 18)](https://img.qammunity.org/2021/formulas/business/college/1d52lidoz6nj4n26c6zr8htbpon4iahx2f.png)
![Current\ breakeven\ point=(720,000)/(12)](https://img.qammunity.org/2021/formulas/business/college/v1vsquu4m1256riv2a8qsgpklep2a7zyud.png)
![Current\ breakeven\ point=60,000\ units.](https://img.qammunity.org/2021/formulas/business/college/uzna4di6m8cmqpfckcch5or7upcrse1y1c.png)
So, we find the new breakeven point by putting formula:
![New\ breakeven\ point=(New\ fixed\ cost)/(selling\ price\ -\ new\ variable\ cost)](https://img.qammunity.org/2021/formulas/business/college/sh0ahlc9flz8cpqz96868tzq9ovx924fl2.png)
![New\ breakeven\ point=(900,000)/(30-15)](https://img.qammunity.org/2021/formulas/business/college/ta3wf0dbpkvm0nxg79fl2fro96cc37yscw.png)
![New\ breakeven\ point=(900,000)/(15)](https://img.qammunity.org/2021/formulas/business/college/7lw095ufzr3qfkd7bqout7bey30vkrbp77.png)
![New\ breakeven\ point=60,000\ units.](https://img.qammunity.org/2021/formulas/business/college/k191w6icbuhv4e5i0zfb6gmt83o7dcq3x4.png)
Now, we see that both the breakeven points current and new are having same units that is 60,000 units. So, break-even point would not change.
Therefore, break-even point in units would not change.
