Shari bought 25lbs of ground beef and made 100 hamburger patties of equal weight. What is the weight of each patty?

25lbs of meat is equal to 400 ounces. If you take the 400 ounces of meat and divide it by the 100 equally sized patties you would have each patty weighing 4 ounces.

Each patty weighs 4 ounces.

Each patty weighs 0.25 lbs
