Answer: Restaurant's monthly breakeven point in sales is $31333.
Step-by-step explanation:
Since we have given that
Number of guests = 20,000
Average sales = $120,000
Contribution margin per guest = $1.50
Let the number of sales be 'x'.
Cost per sales would be
[tex]\dfrac{120000}{20000}\\\\=\$6[/tex]
Margin contributed by 2000 guests would be
[tex]1.50\times 20000\\\\=\$3000[/tex]
So, Revenue function would be
[tex]6x+3000[/tex]
Fixed monthly cost = $ 50,000
Variable cost for 20000 guests = $90000
So, Variable cost per sale would be
[tex]\dfrac{90000}{20000}\\\\=\$4.5[/tex]
So, Cost function would be
[tex]4.5x+50000[/tex]
Breakeven point would be
Cost function = Revenue function
[tex]6x+3000=4.5x+50000\\\\6x-4.5x=50000-3000\\\\1.5x=47000\\\\x=\dfrac{47000}{1.5}\\\\x=\$31333.33\\\\x=\$31333[/tex]
Hence, Restaurant's monthly breakeven point in sales is $31333.
