A small pizza can gives 4 slices, and a large pizza gives 8 slices. George purchased 3 small and 2 large pizzas. George would like to eat 3 pieces. His friend Bob would like to eat one more piece than George. Susie will eat half as many as Bob. Bill, Fred and Mark would each like 3 pieces. How many slices of pizza will be left over? Let's answer step by step:
George has 3 small pizzas * 4 slices = 12 pieces. George also has 2 large pizzas * 8 slices = 16 slices. Total, George has 12 + 16 slices = 28 slices of pizza. Bob will eat 3 slices + 1 = 4 slices. Susie will eat 1 / 2 * 4 slices = 2 slices. Bob, Fred and Mark will eat in total 3 + 3 + 3 = 9 pieces. Total slices of pizza eaten will be 3 + 4 + 2 + 9 = 18 pieces. Total pizza slices remaining will be 28 pieces - 18 = 10 slices left. The answer: 10.
