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: 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. The answer is 59.
Question: Bucky earns money each weekend catching and selling fish. He wants to save up for a new video game, which costs $60. Last weekend he earned $35. He can earn $5 from trout and $4 from blue-gill. He caught five fish this Sunday. If 60% were trout, and the rest were blue-gill, how much more does he need to save before he can buy the game?
Answer: He is $25 short for the game because 60 - 35 = 25. He caught 3 trout because 5 x .6 = 3. He caught 2 blue - gill because 5 - 3 = 2. He earned $15 from the trout because 3 x 5 = 15. He earned $8 from the blue - gill because 2 x 4 = 8. He earned $23 total because 15 + 8 = 23. He is $2 short because 25 - 23 = 2. The answer is 2.
[Question]Charles is jogging while listening to his favorite album. He runs at 6 MPH when he's got music on and 4 MPH when he doesn't. His album is 40 minutes long. How many minutes will it take him to jog 6 miles?
[Answer]He runs at .1 miles per minute because 6 / 60 = .1. While the album is playing he can run 4 miles because 40 x .1 = 4. He has to run 2 miles without the album because 6 - 4 = 2. Without music he runs 1 / 15 miles per minute because 4 / 60 = 1 / 15. He will run the remaining 2 miles in 30 minutes because 2 / (1 / 15) = 30. It will take him 70 minutes in total because 40 + 30 = 70. The answer is 70.
Q: Janice gave all three dozens of pebbles from her trip to her friends. Each of her friends got 4 pebbles. How many friends received pebbles?

Question: Mason is trying to download a 880 MB game to his phone. After downloading 310 MB, his Internet connection slows to 3 MB/minute. How many more minutes will it take him to download the game?
Answer:
First find how many MB are left to download: 880 MB - 310 MB = 570 MB. Then divide that number by the download speed to find the download time: 570 MB / 3 MB / minute = 190 minutes. The answer is 190.
