How many pounds of potatos is needed to make potato salad for 70 people?

The amount of potatoes needed to make potato salad for 70 people depends on several factors, such as the desired serving size and the recipe being used. Here's a general estimate based on a typical serving size of about 1/2 cup of potato salad per person:

Assuming 70 people, each having 1/2 cup of potato salad, you will need approximately 35 pounds (or about 16 kilograms) of potatoes. However, this estimate can vary depending on the recipe and serving size. Some recipes may require more or fewer potatoes, and some people may prefer larger or smaller servings.

It's always a good idea to have some extra potatoes on hand in case you need more, or if some of the potatoes are damaged or unusable. Additionally, if you plan to include other ingredients in the potato salad, such as vegetables, meat, or eggs, you may need to adjust the amount of potatoes accordingly.
