Javier was shopping at the grocery store for some olives. He needed a lot of olives, so he grabbed the large jar off the shelf. Then he noticed the price. The large jar contained 20 oz. of
olives and it cost $3.99. He looked at the small jar of olives. It contained 10 oz. of olives and
cost $1.49. Javier put the large jar back and purchased two small jars of olives.
