Question: Maria found a store that sells handmade sweaters for $30 and a handmade scarf for $20. She wants to buy one for everyone in her family. She will buy 6 sweaters and 6 scarves. If she has saved $500, how much will be left in her savings after buying all these?
Answer with step-by-step thinking: Six sweaters amount to $30 x 6 = $180. Six scarfs amount to $20 x 6 = $120. So, Maria will pay a total of $180 + $120 = $300. Thus, she will be left with $500 - $300 = $200 in her savings.
So the answer is 200.


Question: Sweet Hope hosts a casino with 3 roulette tables labeled A, B, and C. At 6:00 pm, Table B had twice as much money on it as table C, which had $20 more than table A. If there was $40 on table A, how much money was there on all the tables?
Answer with step-by-step thinking: If table C had $20 more than table A, then table C had $20 + $40 = $60. Roulette tables A and C had $60 + $40 = $100. Table B had twice as much money on it as table C, meaning table B had $60 * 2 = $120. Together, the three roulette tables had $120 + $100 = $220.
So the answer is 220.


Question: John writes 3 stories every week. Each short story is 50 pages. He also writes a novel that is 1200 pages each year. Each sheet of paper can hold 2 pages. Over 12 weeks, how many reams of paper does he need to buy if a ream contains 500 sheets?
Answer with step-by-step thinking:
He writes 3 * 50 = 150 pages a week. That means he writes 150 * 52 = 7800 pages of short stories a year. So he writes 7800 + 1200 = 9000 pages a year. So he needs 9000 / 2 = 4500 sheets of paper. That means he needs 4500 / 500 = 9 reams of paper.
So the answer is 3.
