[Question]Anton has three times as many cards in his collection as Heike does. Ann has six times as many cards as Heike does. If Ann has 60 cards, how many more cards does Ann have more than Anton?
[Answer]If Ann has 60 cards, which is six times as many cards as Heike, Heike has 60 / 6 = 10 cards. Anton has three times as many cards in his collection as Heike does, and since Heike has 10 cards, Anton has 10 * 3 = 30 cards. Ann has 60 - 30 = 30 more cards than Anton. The answer is 30.
Q: Daniela goes shopping during a sale. She finds out that the store has 40 percent off on shoes and 20 percent off dresses. If Daniela buys 2 pairs of shoes originally priced at $50 a pair and a dress originally priced at $100, how much money does she spend?
A: Two pairs of shoes at $50 a pair costs $50 x 2 = $100. The shoes are discounted by 40 percent so she only pays 100 - 40 = 60 percent of the original price. Therefore the two pairs of shoes cost $100 x 0.60 = $60. The dress is discounted by 20 percent so she only pays 100 - 20 = 80 percent of the original price. Therefore the dress costs $100 x 0.80 = $80. In total Daniela spends $60 + $80 = $140 for two pairs of shoes and a dress. The answer is 140.
Question: To eat to when she gets full, Michaela needs 20 oranges. Cassandra needs twice as many oranges as Michaela to eat until she gets full. If they picked 90 oranges from the farm today, how many oranges would remain after they've both eaten until they were full?
Answer: Since Michaela needs 20 oranges to eat to her full, and Cassandra eats twice as much to have her full, Cassandra needs 2 * 20 = 40 oranges to eat. They eat 20 + 40 = 60 oranges together to have their fill. If they picked 90 oranges today, after eating 60 together, 90 - 60 = 30 oranges would remain. The answer is 30.

Q: A company was contracted to construct three buildings, with the second building being two times as tall as the first building. The third building had to be three times as tall as the combined height of the first and second buildings. If the first building was 600 feet, calculate the total height of the three buildings together.
A: The second building is two times as tall as the first building, a total of 600 * 2 = 1200 feet. The total height of the first and the second building is 1200 + 600 = 1800 feet. The third building is three times as tall as the combined height of the first and second buildings, which is 1800 * 3 = 5400 feet. Together, the three buildings have a total height of 5400 + 1800 = 7200 feet. The answer is 7200.
Question: It will cost $60 to rent a sailboat and $80 per hour to rent a ski boat. Ken rented a sailboat while Aldrich rented a ski boat. How much more did it cost Aldrich to rent the ski boat than Ken to rent a sailboat for three hours a day in two days?
Answer:
Ken paid $60 x 3 = $180 to rent a sailboat for 3 hours in a day. Aldrich paid $80 x 3 = $240 to rent a ski boat in 3 hours in a day. So Aldrich paid $240 - $180 = $60 more to rent a ski boat than Ken to rent the sailboat each day. Therefore, it cost Aldrich $60 x 2 = $120 more to rent a ski boat than Ken to rent the sailboat in two days. The answer is 120.
