Consider the question. Jame is trying to learn to tear playing cards. He can tear 30 cards at a time. A new deck of cards has 55 cards if you include the jokers and blank cards. He tears cards 3 times a week. If he buys 18 decks how many weeks can he go?
 What is the step-by-step reasoning process to arrive at the answer: 11?
He tears 30 * 3 = 90 cards a week. He bought 55 * 18 = 990 cards. So he can tear for 990 / 90 = 11 weeks.
