Final answer:
To calculate the portion cost of the meatloaf, divide the total cost of making the meatloaf by the number of portions. In this case, the portion cost is $0.006.
Step-by-step explanation:
To calculate the portion cost, we need to determine the total cost of making the meatloaf and divide it by the number of portions. The weight of each portion is 4 grams, and the yield is 50 portions. Therefore, the total weight of the meatloaf is 4 grams * 50 = 200 grams. We need to find the cost of 200 grams of ground beef, which is $0.66 per pound. Converting the weight to pounds gives us 200 grams / 454 grams per pound = 0.44 pounds. The cost of 0.44 pounds of ground beef is 0.44 pounds * $0.66/pound = $0.29. Finally, dividing the total cost by the number of portions gives us $0.29 / 50 = $0.0058 per portion.
Therefore, the portion cost of the meatloaf is $0.0058, which is equivalent to $0.006.
