The yield factor on diced potatoes is 89%. How many pounds of potatoes must be requisitioned to serve 150 guests each a four-ounce portion of diced potatoes?

To determine how many pounds of potatoes need to be requisitioned for 150 guests, each receiving a four-ounce portion of diced potatoes, you'll start by calculating the total weight of the potatoes required before factoring in the yield.

First, convert the portion size from ounces to pounds. Since there are 16 ounces in a pound, a four-ounce portion is equivalent to 0.25 pounds (4 ounces ÷ 16 ounces/pound = 0.25 pounds). Now, for 150 guests, you would multiply the portion size by the number of guests:

0.25 pounds/portion × 150 guests = 37.5 pounds.

This figure of 37.5 pounds represents the total weight of diced potatoes required before accounting for any yield loss.

Next, since the yield factor is 89%, you need to find out how much raw potatoes you must start with to obtain that 37.5 pounds of diced potatoes. To do this, you divide the total weight of the desired product by the yield factor (expressed as a decimal):

37.5 pounds ÷ 0.89 = approximately 42.13 pounds.

This calculation indicates that to yield 37.5 pounds of diced potatoes, around 42.
