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.

Q: There is a 5,200 sq. ft. house and a 7,300 sq. ft. house next to each other. The smaller house is being expanded. If the new total square footage of both houses is 16,000 sq. ft., how much is the smaller house being expanded by, in sq. ft.?
A: Originally, the houses are 7300 + 5200 = 12500 sq. ft. in total. The smaller house will be expanded by 16000 - 12500 = 3500 sq. ft. The answer is 3500.

Q: Angela's contribution is triple Brittany's contribution, and Brittany's contribution is triple Niraj's. If Niraj contributed $80, how much did everyone contribute in total?
A:
Brittany contributed 80 * 3 = 240 dollars. Angela contributed 240 * 3 = 720 dollars. Everyone contributed 80 + 240 + 720 = 1040 dollars in total. The answer is 1040.
