Question

A serving of mashed potatoes is 4oz., the Edible Yield for the potatoes is 72%. How many pounds of raw potatoes should you order to serve 500 people?

Answer 1

Hence 173.75 pounds of raw potatoes are needed for 500 servings.

Explanation:

The edible yield is 72 % means 4 oz in one serving is 72 %

Using ratios to solve

Oz %

4 72

x 100

Using the cross product rule

x= 400/72= 5.56 oz

1 serving has 5.56 oz of raw potatoes

500 serving must have 5.56 *500= 2780 oz of raw potatoes

but 1 0z = 0.0625 pounds

As we need to calculate the pounds we will multiply it with 0.0625

Therefore

2780*0.0625= 173.75 pounds

Hence 173.75 pounds of raw potatoes are needed for 500 servings.
