How many pounds of potatoes to make potato salad for 30 people?

- 6 medium potatoes (about 2 1/2 to 3 pounds) peeled and cubed.

Based on the ingredient ratio (1 medium potato yields 1 cup cooked)

- 30 servings x 1 cup cooked potato per serving = 30 cups of cooked potato.

- Since 1 medium potato yields 1 cup of cooked potato, we need to multiply the number of cups by the number of pounds per medium potato.

-6 (medium potatoes) x (1 cup/potato) = 6 cups per pound.

Calculations

- To get 30 cups, divide the total cups needed by cups per pound.

- 30 cups / 6 cups per pound = 5 pounds.

Therefore, you will need 5 pounds of potatoes to make potato salad for 30 people.
