Question: Tony puts $1,000 in a savings account for 1 year. It earns 20% interest. He then takes out half the money to buy a new TV. The next year, the remaining money earns 15% interest. How much is now in the account?
Answer: After one year he earns $200 in interest because 1,000 x .2 = 200. After one year it has $1,200 in the account because 1,000 + 200 = 1,200. He takes out $600 because 1,200 / 2 = 600. After this it has $600 in it because 1,200 - 600 = 600. She earns $90 in interest because 600 x .15 = 90. The account now has $690 because 600 + 90 = 690. The answer is 690.
[Question]Michael has two brothers. His oldest brother is 1 year older than twice Michael's age when Michael was a year younger. His younger brother is 5 years old, which is a third of the age of the older brother. What is their combined age?
[Answer]The oldest brother is 15 because 3 x 5 = 15. Michael is 8 because if 1 + (Michael's age - 1) x 2 = 15 then Michael's age = 8. Their combined age is 28 because 5 + 15 + 8 = 28. The answer is 28.

Question: Sam bought a heavy safe with a combination lock. There were four rows with twenty gold bars per row arranged in the safe. If each gold bar is worth $20000, calculate the total worth of the gold bars in the safe.
Answer: If there were four rows of twenty gold bars arranged in the safe, the total number of bars in the safe is 4 * 20 = 80 bars. Since each gold bar is worth $20000, the 80 bars are worth 80 * $20000 = $1,600,000. The answer is 1600000.

[Answer]There are 5,000 - 2,000 = 3,000 females that lives in the town. Since thirty percent of the female population wears glasses, 30 / 100 * 3,000 = 900 females wear glasses. The answer is 900.
[Question]Vermont opened up 4 web pages on his web browser and found 12 ads on the first web page and twice as many ads on the second web page as the first web page. When he opened the third web page, he found 24 more ads than the number of ads on the second web page. If the fourth web page had 3/4 times as many ads as the second web page, calculate the total number of ads Vermont clicked on if he clicked on 2/3 of them.
[Answer]
If Vermont found 12 ads on the first web page and twice as many ads on the second web page as the first web page, he found 12 * 2 = 24 ads on the second web page. The first and the second web page had a total of 12 + 24 = 36. Vermont also found 24 more ads on the third web page than the second web page, a total of 24 + 24 = 48 ads. The first three web pages had 48 + 36 = 84 ads. The fourth web page had 3 / 4 times as many ads as the second web page, a total of 3 / 4 * 24 = 18 ads. In all the web pages Vermont opened, he found 84 + 18 = 102 ads. If he clicked on 2 / 3 of them, he clicked on 2 / 3 * 102 = 68 ads. The answer is 68.
