Question: Lee is saving up for a new pair of sneakers which cost $90. He already has $15 saved. He plans to sell his old action figures to make the rest. If he sells 10 action figures and still has $25 left after buying the sneakers how much did he charge per action figure?
Answer: Before buying the shoes he had $115 dollars because 90 + 25 = 115. He earned $100 from selling action figures because 115 - 15 = 100. He sold them each for $10 because 100 / 10 = 10. The answer is 10.

Question: A pair of dogs are barking back and forth at each other from across the street. The poodle barks twice for every one time the terrier barks. The terrier’s owner hushes it every second time it barks. She has to say “hush” six times before the dogs stopped barking. How many times did the poodle bark?
Answer: The terrier barked twice as many times as it was told to hush, so it barked 6 * 2 = 12 times. The poodle barked two times for every terrier bark, so it barked 12 * 2 = 24 times. The answer is 24.

Question: Maria wants to buy a brand new bike. The retail price at the bike shop stands at $600. She saved $120 toward the purchase. As this was not enough, she asked her mother to give her the remaining amount. Her mother offered her $250 and told her that she needs to earn the rest working during the holidays. How much money must Maria earn to be able to buy the bike she wants?
Answer:
Maria has $120 and received $250 from her mother. So she has 120 + 250 = $370. As the price of the bike stands at $600, Maria needs 600 – 370 = $230 more to buy the bike. The answer is 230.
