The food committee for the end of year class picnic plans to serve 4 oz hamburger patties how many pounds meat should be purchased make 125 hamburgers?

To calculate the amount of meat needed, we need to determine the total weight of the hamburger patties required. Since each hamburger patty weighs 4 ounces, and we need 125 hamburgers:

Total weight of hamburger patties = Number of hamburgers × Weight per patty

Total weight = 125 × 4 ounces

Converting ounces to pounds by dividing by 16:

Total weight = 125 × 4 / 16 pounds

Total weight = 500 / 16 pounds

Total weight ≈ 31.25 pounds

Therefore, approximately 31.25 pounds of meat should be purchased to make 125 hamburgers with 4 oz patties each.
