Question: If you buy a dozen of doughnuts, it costs $8; but if you buy 2 dozens, it costs $14. How much will you save from buying 3 sets of 2 dozens than buying 6 sets of 1 dozen?

[Question]Baez has 25 marbles. She loses 20% of them one day. Then a friend sees her and gives her double the amount that Baez has after she lost them. How many marbles does Baez end up with?
[Answer]She loses 5 marbles because 25 x .2 = 5. She has 20 marbles after this because 25 - 5 = 20. Her friend gives her 40 marbles because 20 x 2 = 40. Adding those marbles to the 20 she had before, she ends up with 40 marbles + 20 marbles = 60 marbles. The answer is 60.
Q: James won a money prize at a charity raffle. He donated half of his winnings back to the charity, then spent $2 on a hot dog to celebrate his win. He had $55 left over. How many dollars did he win?
A: Let W be equal to James's raffle winnings. He donated half his winnings, so he had W - W / 2 = W / 2 left. He then spent $2 on a hot dog, so W / 2 - 2 = $55. Thus, half his winnings is W / 2 = 55 + 2 = 57. James won W = 57 * 2 = $114. The answer is 114.
Question: There are three buckets full of oranges. There are 22 oranges in the first bucket, 17 more oranges in the second bucket and 11 fewer oranges in the third bucket than in the second. How many oranges are there in all the buckets?
