[Question]Simon collected treasures on the beach during his summer vacation. He collected a bucket of pearly seashells, a jar full of smooth sea glass, and a bag of ten sand dollars. If the jar holds three times as many pieces of glass as the bag does sand dollars, and the bucket holds five times as many seashells as the jar holds pieces of glass, how many treasures did Simon find on the beach?
[Answer]The jar holds 3 * 10 = 30 pieces of glass. The bucket holds 5 * 30 = 150 seashells. Simon found 10 + 30 + 150 = 190 treasures on the beach. The answer is 190.

Question: A math teacher had $100 to buy three different types of calculators. A basic calculator costs $8. A scientific calculator costs twice the price as the basic while a graphing calculator costs thrice the price as the scientific. How much change did she receive after buying those three different types of calculators?
Answer: A scientific calculator costs $8 x 2 = $16. A graphing calculator costs $16 x 3 = $48. So, she spent $8 + $16 + $48 = $72 for the three calculators. Therefore, the math teacher received $100 - $72 = $28 change. The answer is 28.
Q: Niles is collecting his book club's annual fees. Each of the six members pays $150/year towards snacks, plus $30 each for six hardcover books and $12 each for six paperback books. How much money does Niles collect in total?
A:
First find the cost per member of the hardcover books: $30 / book * 6 books = $180. Then find the cost per member of the paperback books: $12 / book * 6 books = $72. Then find the total cost per member: $180 + $72 + $150 = $402 / member. Now find the total amount of money by multiplying the cost per member by the number of members: $402 / member * 6 members = $2412. The answer is 2412.
