[Question]Abigail spent 60% of her money on food, and 25% of the remainder on her phone bill. After spending $20 on entertainment, she is left with $40. How much money did Abigail have initially?
[Answer]Abigail had $20 + $40 = $60 left after paying her phone bill. The $60 is 100% - 25% = 75% of the remainder of her money after spending for food. Since 75% is $60, then 1% is $60 / 75 = $0.80. Thus, Abigail had $0.80 x 100 = $80 left after she spent money on food. The $80 is 100% - 60% = 40% of her original money. So 1% is $80 / 40 = $2. Therefore, Abigail initially had $2 x 100 = $200. The answer is 200.
Q: Lucille is wondering who has the tallest house between her and her neighbors. His family's house is 80 feet tall. One neighbor's house is 70 feet tall. Another neighbor's house is 99 feet tall. How much shorter is Lucille's house than the average height?
A: The houses are 249 feet in total because 70 + 80 + 99 = 249. The average height is 83 feet because 249 / 3 = 83. Her house is 3 feet shorter because 83 - 80 = 3. The answer is 3.

[Question]Sasha heard that planting trees helps to reduce the local temperature. For each tree planted, the temperature drops .1 degree. A tree costs $6 to plant. If she got the local temperature to drop from 80 to 78.2, how much did it cost to plant the trees?
[Answer]The temperature dropped 1.8 degrees because 80 - 78.2 = 1.8. She planted 18 trees because 1.8 / .1 = 18. It cost $108 to plant the trees because 18 x 6 = 108. The answer is 108.
[Question]In a city, the number of people living per cubic yard is 80. How many more people are in a city with 9000 cubic yards than a city with 6400 cubic yards?
