Question: Jake amasses a fortune of 80 bitcoin. He donates 20 bitcoins to charity. He then gives half of all the bitcoins to his brother. After that, he triples the number of bitcoins he has. Then he donates another 10 coins. How many coins does he have?
Answer: Step-by-step reasoning process: He had 80 - 20 = 60 after the donation. He kept 60 / 2 = 30 after giving half to his brother. So he has 30 * 3 = 90 coins. He then does 1 more donation and has 90 - 10 = 80 coins left.
So the answer is 80.

Question: Pam has 10 bags of apples. Each of her bags has as many apples as 3 of Gerald's bags. If Gerald's bags have 40 apples each, how many apples does Pam have?

Question: A publishing house decides to create a contest for new writers and will award a total of $800 in prizes to the 18 novels with the most votes. First place will get $200, second place will get $150, third place $120 and the rest of the awards will be paid with the same amount of money. How much money will each writer earn from fourth place onwards?
Answer:
Step-by-step reasoning process: The first three cash prizes sum to $200 + $150 + $120 = $470. The remaining amount of cash prizes to be distributed is $800 - $470 = $330. The number of novels left to be awarded is 18 – 3 = 15 novels. So each writer from 4th to 18th will earn $330 / 15 = $22.
So the answer is 22.
