Lisa is having a party. She wants to have pizza for her friends. She is having 5 friends over for her party. Each pizza serves eight people 1 slice of pizza. She wants everyone to have 3 pieces of pizza. How many pizzas will she have to order? Will she have any leftover pieces? (Don't forget to include Lisa, when ordering the pizza).
6 X 3 = 18 slices of pizza; 8 x 3 = 24 slices; 24 - 18 = 6 slices; Lisa will have to order 3 pizzas. She will have 6 pieces left over.
