During the night, Jen woke up hungry. She went to the kitchen and ate two of the cookies that they had made. She then divided the rest of the cookies into two even piles. Jen took one pile and placed these cookies in a cookie tin which she hid in a cabinet before going back to bed.

A short time later, Maria woke up and went down to the kitchen. She ate two cookies because she was hungry, then split the remaining cookies into two equal piles. She put one pile in a plastic bag to take home for her family and hid it in her backpack before going back to bed.

In the morning, the girls were surprised to find only 10 cookies left in the pile for the bake sale. “I only ate a couple of cookies because I was hun- gry,” said Jen. “So did I,” said Maria. “Well, we might as well split the rest,” suggested Jen. “Okay,” said Maria, “and then we can get started baking more for the bake sale.”

- How many cookies did the girls bake for the bake sale?
- How many cookies did each girl take?
- If they split the remaining cookies fairly, did each girl get her fair share

of the cookies? Explain.
