Answer and Explanation:
The computation of total restaurant sales and the sales of each product line is shown below:-
Sales = (Net income + Fixed costs + variable costs)
Let sales be "x"
Sales = ($1,417,000 + $116,000) ÷ 0.51
= $3,005,882.35
Total sales Contribution Contribution Each product
Margin Margin ratio sales
Appetizers 15% 70% 10.50% $450,882.353
Main entrees 50% 25% 12.50% $1,502,941.18
Desserts 10% 80% 8.00% $300,588.235
Beverages 25% 80% 20% $751,470.588
51.00% $3,005,882.36
For computing the Contribution Margin ratio we simply multiply the total sales with contribution margin of every product.
