[Question]: Jake and Penny are hunting snakes. Jake's snake is 12 inches longer than Jenny's snake. If the two snakes have a combined length of 70 inches, how long is Jake's snake?
[Answer]: Let j be the length of Jake's snake and p be length of Penny's snake. We know that j + p = 70, and j = p + 12. We can substitute the second equation into the first equation to get p + 12 + p = 70. Combining like terms, we get 2p + 12 = 70. Subtracting 12 from both sides, we get 2p = 58. Dividing both sides by 2, we get p = 58 / 2 = 29 inches. Penny's snake is 29 inches. Substituting that length in to the equation j = p + 12, we get j = 29 inches + 12 inches = 41 inches.
So the answer is 41.

[Question]: Jenny wants to read 3 books in the next 10 days. She can read 100 words per hour. If the first book has 200 words, the second book has 400 words, and the third book has 300 words, how many minutes per day, on average, should she spend reading?
[Answer]: She wants to read 200 + 400 + 300 = 900 pages total. She needs to spend 900 / 100 = 9 hours reading in the next three weeks. In minutes, she will need to spend 9 * 60 = 540 minutes. Thus, she should spend 540 minutes / 10 days = 54 minutes per day reading.
So the answer is 54.

[Question]: A king gets a crown made that costs $20,000. He tips the person 10%. How much did the king pay after the tip?
[Answer]:
The tip was 20000 * .1 = $2000. So the total cost was 2000 + 20000 = $22000.
So the answer is 22000.
