Q: Jerry wakes up one morning and finds the thermostat set to 40 degrees. He set it to double the initial temperature. His dad notices, yells at Jerry, and reducing the temperature by 30 degrees. Later, Jerry's mother reduces the temperature by 30%, before his sister increases it by 24 degrees. What's the final temperature?
A: 59
Step-by-step reasoning process: First double the initial temperature: 40 degrees * 2 = 80 degrees. Then reduce that amount by 30 to reflect the dad's change: 80 degrees - 30 degrees = 50 degrees. Then multiply that number by 30% to find how much Jerry's mother reduces the temperature: 50 degrees * .3 = 15 degrees. Now subtract 15 degrees from 50 degrees to find the temperature after the mother's change: 50 degrees - 15 degrees = 35 degrees. Finally, add 24 degrees to find the final temperature: 35 degrees + 24 degrees = 59 degrees.


Q: During a fundraiser, each of the 20 members of a group sold candy bars which costs $0.50 each. If each member sold an average of 8 candy bars, how much money did they earn from their candy bars sales, in dollars?
A: 80
Step-by-step reasoning process: The group was able to sell 20 x 8 = 160 candy bars. So, they got 160 x $0.5 = $80 from their candy bars sales.


Q: Lightning McQueen, the race car, cost 140000$. Mater only cost 10 percent of that, and Sally McQueen cost triple what Mater costs. How much does Sally McQueen cost?
A: 42000
Step-by-step reasoning process: Mater:140000(.10) = 14000$. Sally:14000(3) = 42000$.


Q: Hazel walked 2 kilometers in the first hour. If she walked twice as far in the second hour, how far did she walk for 2 hours?
A: 6
Step-by-step reasoning process: Hazel walked 2 x 2 = 4 kilometers in the second hour. So, she walked 2 + 4 = 6 kilometers for 2 hours.
