Analyzing changes to break$-$even point

C$2$

Zulu sells its waterproof phone case for $$90$ per unit. Fixed costs total $$200,000,$ and variable costs are $$40$ per unit. $($a$)$ Compute its break$-$even in units. $($b$)$ Will the break$-$even point in units increase or decrease in response to each of the following independent changes?

Change

$$Fixed costs increase to $$225,000........$

$$Variable costs decrease to $$26$ per unit

$$Selling price per unit decreases to $$80.$

Break$-$Even in Units will:

Change

$$Variable costs increase to $$58$ per unit $....$

$$Fixed costs decrease to $$150,000......$

$$Selling price per unit increases to $$120$

Break$-$Even in Units will:
