[Question]Wally buys bears at the park. A bear is priced at $4.00 for the first bear and a discount of 50 cents per bear is given after that. How much does Wally pay for 101 bears?
[Answer]If the price of an additional bear drops by fifty after the first purchase, the price of each additional bear is $4.00 - $0.50 = $3.50. Since Wally bought 101 bears, he was charged fifty cents less on 101 - 1 = 100 bears. The total cost for the 100 bears is 100 * $3.50 = $350. For the 101 bears, Wally paid a total of $350 + $4 = $354. The answer is 354.

[Question]John decides to learn how to play the piano. He buys a piano for $500. He then hires a teacher for 20 lessons at $40 per lesson but ends up getting a 25% discount. How much did everything cost?
[Answer]The normal price of the lessons would be 20 * 40 = $800. The discount saves him 800 * .25 = $200. So the lessons cost him 800 - 200 = $600. That means everything costs 500 + 600 = $1100. The answer is 1100.

[Question]Antoinette weighs 7 less kilograms than twice Rupert's weight. Together they weigh 98 kilograms. How many kilograms does Antoinette weigh?
[Answer]Let R = Rupert's weight. Antoinette = 2R - 7. R + 2R - 7 = 98. 3R = 105. Rupert = 35 kg. Antoinette = 2 * 35 - 7 = 63 kg. Antoinette weighs 63 kilograms. The answer is 63.

[Question]April went to a concert that has two bands. 2/3 of the audience was there for the second band and 1/3 was there for the first band. 50% of the audience there for the second band is under the age of 30. Of this group, 60% are women and there are 20 men. How many people are at the concert?
[Answer]
Of the under - 30s there for the second band, 40% are men because 100 - 60 = 40. There are fifty under - 30s there for the second band because 20 / .4 = 50. There are 100 people there to see the second band because 50 / .5 = 100. There are 150 people at the concert because 100 / (2 / 3) = 150. The answer is 150.
