Q: 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?
A: 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. The answer is 7.

Q: John has to pay taxes. He earned $100,000 for the year. He has $30,000 in deductions. The first $20,000 of taxable income is taxed at 10%. The rest is taxed at 20%. How much does he pay in taxes?
A:
His taxable income is 100,000 - 30,000 = $70,000. So he pays 20,000 * .1 = $2000 tax at the lower rate. He has to pay 70,000 - 20,000 = $50,000 at the higher rate. The taxes for that is 50,000 * .2 = $10,000. So his total tax bill is 10,000 + 2,000 = $12,000. The answer is 12000.
