Calculating the Amount of Pork Roast Needed for 600 Portions

06 Apr 2022

Explanation:

Calculating Total Amount Needed: To begin, we know that each portion weighs 3 oz and there are 600 portions needed. Therefore, the total weight required is 1800 oz (3 oz * 600).

Converting to Pounds: Since 1 lb equals 16 oz, we convert the total amount to pounds which gives us 112.5 lbs (1800 oz / 16).

Adjusting for Shrinkage: To accommodate the 15% shrinkage factor during cooking, we divide the desired amount by 0.85 (100% - 15% = 85% or 0.85 in decimal form). This results in a total raw weight requirement of approximately 132.35 lbs.

Final Answer Selection: Among the answer choices provided, the closest amount to the calculated raw weight after shrinkage is 133 lbs, which is option c.
