Question: Tommy's mother lets him ride his bike 2 blocks north of his block, 3 blocks east, 2 blocks west, and 2 blocks south. His friend's father lets his friend ride his bike 80 square blocks. How many times greater is the area his friend can ride in compared to Tommy?
Answer: Tommy's area is 5 blocks wide because 3 + 2 = 5. His area is 4 blocks tall because 2 + 2 = 4. The total area is 20 square blocks because 5 x 4 = 20. His friend's area is 4 times bigger because 80 / 20 = 4. The answer is 4.
[Question]There are 50 marbles in a box which has a mixture of white, red and blue marbles. There were originally 20 white marbles and an equal number of red and blue marbles. Jack removes a number of marbles equal to double the difference between the number of white marbles and the number of blue marbles. How many marbles are left in the box?
[Answer]20 of 50 marbles are white so there are 50 - 20 = 30 red and blue marbles. The number of red marbles and blue marbles is the same, so there are 30 / 2 = 15 of each color. The difference between the number of white marbles and blue marbles is 20 - 15 = 5. Double the difference is 5 * 2 = 10 marbles. 10 marbles are removed to leave 50 - 10 = 40 marbles. The answer is 40.
Q: Joe's pizzeria has an amazing promotion. If you buy any regular large pizza you can get the next 3 medium pizzas for $5 each. What are your total savings if the regular medium pizza price is $18 and you take full advantage of the promotion?
A: If one medium pizza costs $18 and with the promotion I can buy one for $5, then I'm saving $18 - $5 = $13 on each medium pizza. If I take full advantage of the promotion, that means I bought all 3 medium pizzas, therefore I saved a total of 3 * $13 = $39 in total. The answer is 39.
Question: Mike spent 37 dollars on notebooks. He bought a total of 12 notebooks. He bought 3 red notebooks at 4 dollars each, 2 green notebooks at 2 dollars each, and the rest were blue notebooks. How much does each blue notebook cost?
Answer: He bought 12 - 3 - 2 = 7 blue notebooks. He paid 3 * $4 = $12 for red notebooks. He paid 2 * $2 = $4 for green notebooks. He spent $37 - $12 - $4 = $21 on blue notebooks. Each blue notebook costs $21 / 7 = $3. The answer is 3.
[Question]My dog was born when I was 15 years old. Two years from now, my dog will turn 4 years old. How old am I now?
[Answer]In 2 years, my dog will be 4 years old, so my dog is 4 - 2 = 2 years old now. So I am 15 + 2 = 17 years old now. The answer is 17.

Her oldest wants 2 strings cheeses a day for 5 days so 2 * 5 = 10 string cheeses. Her youngest wants 1 string cheese a day for 5 days so 1 * 5 = 5 string cheeses. Together they want 10 + 5 = 15 string cheeses a week. Over 4 weeks, her kids will eat 15 string cheeses so 4 * 15 = 60 string cheeses. The bags have 30 per pack and she needs 60 so 60 / 30 = 2 packs of string cheese. The answer is 2.
