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: 200
Reverse engineering the 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?
Reasoning and answer: They ran 2,400 meters because 24 laps x 100 m / lap = 2400 m. They ran 200 meters per minute because 2400 m / 12 min = 200 m / min. For every minute they ran they earned an average of $7 because $3.5 / 100m x 200 m / min = $7 / min.
The answer: 7

After spending money on a shirt, Lily had $55 - $7 = $48 left. She spent $7 x 3 = $21 on another store. Therefore, she only has $48 - $21 = $27 left on her account.
The answer: 27
Reverse engineering the question:
Lily had $55 in her account. She spent $7 on a shirt. She then went to another shop and spent thrice as much as she spent on a shirt. How much money is left in Lily's account?
