Question: Andy is making fudge. First he needs to raise the temperature of the candy mixture from 60 degrees to 240 degrees. Then he needs to cool it down to 170 degrees. If the candy heats at 5 degrees/minute and cools at 7 degrees/minute, how long will it take for the candy to be done (in minutes)?
Answer: First find the total number of degrees the candy needs to heat up: 240 degrees - 60 degrees = 180 degrees. Then divide that amount by the rate the candy heats up: 180 degrees / 5 degrees / minute = 36 minutes. Then find the number of degrees the candy needs to cool down: 240 degrees - 170 degrees = 70 degrees. Then divide that by the rate the candy cool down: 70 degrees / 7 degrees / minute = 10 minutes. Then add the time for the candy to heat to the time for it to cool to find the total time: 10 minutes + 36 minutes = 46 minutes. The answer is 46.

Question: The cheerleading coach is ordering new uniforms. There are 4 cheerleaders who need a size 2, a certain number who need a size 6, and half that number who need a size 12. If there are 19 cheerleaders total, how many cheerleaders need a size 6?
Answer: Let s be the number of cheerleaders who need a size 6 and t be the number who need a size 12. We know that s = 2t and s + t + 4 = 19. Substituting the first equation into the second equation, we get 2t + t + 4 = 19. Combining like terms, we get 3t + 4 = 19. Subtracting 4 from both sides, we get 3t = 15. Dividing both sides by 3, we get t = 5. Substituting that value back into the equation s = 2t, we get s = 2 * 5 = 10. The answer is 10.

Question: Mikail's birthday is tomorrow. He will be 3 times older than he was when he was three. On his birthday, his parents give him $5 for every year old he is. How much money will they give him?
Answer: Mikail is 9 because 3 x 3 = 9. He will get $45 because 9 x $5 = $45. The answer is 45.

Question: Paul goes fishing every Saturday. Last week he was able to catch 5 fish for every 2 hours he was fishing. How many fish did he catch when he was fishing for 12 hours?
Answer:
Paul caught 5 fish 12 / 2 = 6 times that day. So he was able to catch in total 6 * 5 = 30 fish. The answer is 30.
