Answer:
The BEP will decrease, which is good.
The reason is that C90B has a better profit margin than Y45E so if the sales shift toward C90B the Contribution mix margin ratio will be higher and it will be easy to pay fixed cost and make a gain
Explanation:
C90B
sales 37,000
variable expenses 9,250
contribution margin 27,750
CM 0.75
Y45E

variable expenses 16,335
contribution 13,365
CM 0.45
