Mark is running for an election and wins 70% of the votes in an area with 100,000 voters. He got twice as many total votes in the remaining area. How many votes did he get in total? Give the rationale and then the answer.
Let's think step by step. He got 100,000 * .7 = 70,000 votes from the first area. He got 70,000 * 2 = 140,000 votes in the remaining areas. So in total he got 140,000 + 70,000 = 210,000 votes.. The answer is: 210000.

James builds a 20 story building. The first 10 stories are each 12 feet tall each. The remaining floors are each 3 feet taller. How tall is the building? Give the rationale and then the answer.
Let's think step by step. The first 10 floors are 10 * 12 = 120 feet. There are a remaining 20 - 10 = 10 stories. They are each 12 + 3 = 15 feet. So those stories are 15 * 10 = 150 feet. So the total height is 120 + 150 = 270 feet.. The answer is: 270.

An elementary school teacher is making Halloween goodie bags for her class. She wants the bags to be personalized, so she surveys her students asking whether they'd like a vampire-themed bag or a pumpkin-themed bag. Of her 25 students, 11 indicate they want the vampire-themed bag and 14 indicate they want the pumpkin-themed bag. The store the teacher shops at sells packs of 5 of each theme at a price of $3 per package, as well as individual bags of each theme at a price of $1 each. What is the least amount of money the teacher can spend on the bags if she buys every student the theme they requested? Give the rationale and then the answer.
Let's think step by step. Because it is cheaper to buy the packs of 5, the teacher should satisfy the 11 students who want the vampire theme with 2 packs of 5 and 1 individual bag. This will cost the teacher 2 * 3 + 1 * 1 = $7. Similarly, the 14 students who want a pumpkin - themed bag can be satisfied by 2 packs of 5 and 4 individual bags at a cost of 2 * 3 + 4 * 1 = $10. Therefore, the teacher must spend 7 + 10 = $17.. The answer is: 17.
