Mrs. Gainey planned a dinner for 15 people this Thanksgiving. She bought 22.5 lbs of turkey, plus potatoes, cranberry salad, rol
ls and all of the traditional holiday food. Unfortunately, her daughter forgot to tell her that she was bringing three of her college friends. If Mrs. Gainey wanted to feed each person the same amount of turkey that she had originally planned, how much additional turkey must she purchase to accommodate these additional guests? Express your answer as a decimal to the nearest tenth. What percent is each person’s intended serving of turkey reduced?
Each person was to have 1.5 pounds of turkey, but, with the extra people she would have to buy an additional 4.5 pounds of turkey. If she didn’t buy anymore turkey then everyone would get 1.25 pounds of turkey, which is about 1/6 less of what they would have originally gotten. 1/6 is equal to 16.7% or 0.167.
