Question: Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend?
Answer: Step-by-step reasoning process: The goats cost 3 * 400 = $1200. He buys 3 * 2 = 6 llamas. Each llama cost 400 * 1.5 = $600. So he spends 600 * 6 = $3600 on llamas. So the total cost was 1200 + 3600 = $4800.
So the answer is 4800.

Question: At a station, a train comes every 5 minutes leaving 200 passengers and taking 320 others. How many different passengers step on and off a train at the station within an hour?
Answer: Step-by-step reasoning process: At every passenger exchange there are 200 + 320 = 520 different people. One hour is 60 minutes, so during one hour, a train comes 60 minutes / hour / 5 minutes / train = 12 times. So during one hour, 12 trains * 520 passengers / train = 6240 different passengers step on and off the train.
So the answer is 6240.

Question: This evening in the nighttime sky over Texas, Mars can be seen until 12:10 AM. Jupiter does not appear until 2 hours and 41 minutes later, and Uranus does not appear until 3 hours and 16 minutes after Jupiter makes its first appearance. How many minutes after 6:00 AM does Uranus first appear in the evening sky over Texas this evening?
Answer: Step-by-step reasoning process: Jupiter appears 2 hours and 41 minutes after 12:10 AM, which can be calculated in two parts;. 2 hours after 12:10 AM is 12:10 + 2:00 = 2:10 AM. And an additional 41 minutes after 2:10 AM is 2:10 + 0:41 = 2:51 AM. Uranus appears 3 hours and 16 minutes after 2:51 AM, which can be calculated in two parts:. 3 hours after 2:51 AM is 2:51 + 3:00 = 5:51 AM. And 16 minutes after 5:51 AM is 5:51 + 0:16 = 5:67 AM = 6:07 AM. Thus, 6:07 AM is 7 minutes after 6:00 AM.
So the answer is 7.
