Answer:
Helen's break-even point would occur at 200 cards sold.
Explanation:
Hi, in order to find the break even point (BEP) in units, we need to use the following formula.
[tex]BEP=\frac{FixedCosts}{Price-Cost(var)}[/tex]
Everything should look like this.
[tex]BEP=\frac{400}{3-1} =200[/tex]
So, the BEP for Helen is 200 cards sold.
Best of luck.
