The pizzeria sells small pizzas for $2 and large pizzas for $8. They sold $40 in pizzas. If they sold 8 small pizzas, how many large pizzas did they sell?
Let's think: They earned 8 * 2 = $16 from the small pizzas. The large pizzas earned 40 - 16 = $24. They sold 24 / 8 = 3 large Pizzas.. The answer is: 3.

Jon decides to take up baseball. He can throw a fastball at 80 miles per hour.  He goes through intense training 4 times for 4 weeks each time and at the end of the last one he can throw a ball 20% faster. How much speed (in mph) did he gain per week, assuming he gained an equal amount of speed (in mph) each week?
Let's think: He threw the ball 80 * .2 = 16 mph faster. He was training for 4 * 4 = 16 weeks. So he gained 16 / 16 = 1 mph per week.. The answer is: 1.

Bill the miner discovers a vein of fool's gold. He successfully sells 8 ounces to a merchant, but when he tries to sell to the sheriff he's arrested, fined $50 and run out of town on a rail. If Bill earned $9 for every ounce of fool's gold he sold, how much money is he left with?
Let's think: First find the total amount of money Bill made from the merchant: 8 ounces * $9 / ounce = $72. Then subtract the fine to find how much money he was left with: $72 - $50 = $22.. The answer is: 22.

Hadley wore his cowboy boots everywhere. He walked 2 miles to the grocery store in his boots. Then he walked 1 less than two miles to the pet store in his boots. Then, he walked one less than four miles back home in his boots. How far, in miles, did Hadley walk in his boots?
Let's think:
After he walked 2 miles to the grocery store, he walked one less than two miles to the pet store, adding 2 - 1 = 1 mile to his journey. To complete his journey, he walked one less than four miles to return home, adding 4 - 1 = 3 miles. to his journey. In total, Hadley walked 2 + 1 + 3 = 6 miles.. The answer is: 6.
