Answer:
Hence 173.75 pounds of raw potatoes are needed for 500 servings.
Step-by-step 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.
