Question: Timmy's parents have a 2 car garage, which has both cars inside it. Also inside is a riding lawnmower, a bicycle for Timmy as well as each of his parents, a tricycle for Timmy's little brother Joey, and a unicycle that Timmy's dad practices riding on. How many wheels in total are in this garage?
Answer: Each car in the garage has 4 wheels, for a total of 4 * 2 = 8 wheels. The riding lawnmower has 4 wheels, bringing the total up to 8 + 4 = 12 wheels. The bicycles have 2 wheels each and there are 3 of them, for 3 * 2 = 6 wheels, bringing the total to 12 + 6 = 18. The tricycle has 3 wheels, and the unicycle has 1 wheel, bringing the total up to 18 + 1 + 3 = 22 wheels. The answer is 22.
