Answer:
It would need 549 guests to break even.
Explanation:
The first step will be know the Contribution Margin:
[tex]Sales \:Revenue - Variable\: Cost = Contribution \:Margin[/tex]
Variable Cost
Food 120
Other 8
Total 128
Next we do the Contribution Margin, which represent how much cash each guest generates to pay the fixed cost
500- 128 = 372
Then we Calculate the total fixed cost we need to pay
Rental 150,000
Advertising 50,000
Entertainment 4,000
Total 204,000
Now we calculate the Break Even Point in units (for this case, in guests)
[tex]\frac{Fixed\:Cost}{Contribution\: Margin} = Break \: Even \: Point_{guests}[/tex]
[tex]\frac{204,000}{372} = 548.34[/tex]
It would need 549 guests to break even.
