One afternoon Mrs. Crockett baked cookies for her bridge club meeting that evening. She left the cookies on the kitchen
table to cool while she went to the store. She had just left when her oldest son discovered the cookies and took one-third
of them plus an extra 1/3 of a cookie along with him to football practice.
Just after he left, her middle son came into the kitchen, grabbed one-third of the cookies plus an extra 2/3 of a cookie and, happily munching, went off to band practice. No sooner had he gone than Mrs. Crockett’s youngest son found the cookies and also took one-third of them plus an extra cookie along with him when he went out to play with his friends.
When Mrs. Crockett returned from the store, she found that there were only 15 cookies left. How many cookies had she baked?
