How many pounds of tomato sauce do you needed to make spaghetti feed 80 people?

To calculate the amount of tomato sauce needed to make spaghetti for 80 people, consider the following factors:

1. Serving Size: Assume a standard serving size of 1/2 cup of tomato sauce per person.

2. Number of Servings: Multiply the number of people (80) by the serving size (1/2 cup) to determine the total number of servings needed.

80 people x 1/2 cup per person = 40 cups of tomato sauce

3. Volume to Weight Conversion: 1 cup of tomato sauce approximately weighs 8 ounces.

40 cups of tomato sauce x 8 ounces per cup = 320 ounces of tomato sauce

4. Convert Ounces to Pounds: There are 16 ounces in 1 pound.

320 ounces of tomato sauce / 16 ounces per pound = 20 pounds of tomato sauce

Therefore, you will need approximately 20 pounds of tomato sauce to make spaghetti for 80 people. However, it's always better to prepare a slight excess to account for variations in personal preferences and appetites.
