[Question]Suzanne wants to raise money for charity by running a 5-kilometer race. Her parents have pledged to donate $10 for her first kilometer and double the donation for every successive kilometer. If Suzanne finishes the race, how much money will her parents donate?
[Answer]For the 2nd kilometer, the donation will be $10 * 2 = $20. For the 3rd kilometer, the donation will be $20 * 2 = $40. For the 4th kilometer, the donation will be $40 * 2 = $80. For the final kilometer, the donation will be $80 * 2 = $160. For the entire race the donation will be $10 + $20 + $40 + $80 + $160 = $310. The answer is 310.
Q: A cleaning company produces two sanitizer sprays. One spray kills 50% of germs, and another spray kills 25% of germs. However, 5% of the germs they kill are the same ones. What percentage of germs would be left after using both sanitizer sprays together?
A: After the first spray kills 50% of germs, there will be 100 - 50 = 50% left. The second spray kills 25%, but 5% have already been killed by the 50% spray, so it kills 25 - 5 = 20%. After the second spray kills 20% of the remaining germs, there will be 50 - 20 = 30% left. The answer is 30.
Question: Tommy goes for a run around his neighborhood and decides to calculate how many wheels he saw. All the trucks in his neighborhood have 4 wheels and all the cars in his neighborhood also have 4 wheels. If he saw 12 trucks and 13 cars, how many wheels did he see?
Answer: He saw 25 total vehicles because 12 plus 13 equals 25. He saw 100 wheels because 25 times 4 equals 100. The answer is 100.
[Question]A mother is making her own bubble mix out of dish soap and water for her two-year-old son. The recipe she is following calls for 3 tablespoons of soap for every 1 cup of water. If the container she hopes to store the bubble mix in can hold 40 ounces of liquid, and there are 8 ounces in a cup of water, how many tablespoons of soap should she add to the container (assuming that the soap itself doesn't count towards the capacity of the container)?
[Answer]The 40 - ounce container can hold 40 / 8 = 5 cups of water. This means that 5 * 3 = 15 tablespoons of soap should be used, since each cup of water requires 3 tablespoons of soap. The answer is 15.
Q: A train travels 270 miles in 3 hours. At the same rate, how many additional hours would it take to travel an additional 180 miles?

Question: Mary is chopping up some old furniture to make firewood. Chairs make 6 sticks of wood, tables make 9 sticks of wood, and stools make 2 sticks of wood.

First find the total sticks from the chairs: 6 sticks / chair * 18 chairs = 108 sticks. Then find the total sticks from the tables: 9 sticks / table * 6 tables = 54 sticks. Then find the total sticks from the stools: 2 sticks / table * 4 stools = 8 sticks. Then add up the total number of sticks she gets: 108 sticks + 54 sticks + 8 sticks = 170 sticks. Then divide the total number of sticks by the number of sticks she burns per hour to find the total number of hours she can keep warm: 170 sticks / 5 sticks / hour = 34 hours. The answer is 34.
