Reasoning and answer: If 40% of the balls had holes in them and could not inflate, their number was 40 / 100 * 100 = 40. The remaining balls that Nova could inflate were 100 - 40 = 60. While inflating, 20% of the good soccer balls were overinflated and exploded up, a total of 20 / 100 * 60 = 12. The number of soccer balls that inflated successfully and could be used is 60 - 12 = 48.
The answer: 48

Henry gets paid 5 + 13 = $18 for each bike painted and sold. In total, Henry will be paid 8 * 18 = $144 for painting and selling 8 bikes.
The answer: 144
Reverse engineering the question: For every bike Henry sells, he is paid $8 more than he is paid to paint the bike. If Henry gets $5 to paint the bike, how much does he get paid to sell and paint 8 bikes?
Reasoning and answer: The federal government takes out 1 / 3 * 450 = 150 dollars. The state takes out 0.08 * 450 = 36 dollars. Then the final amount remaining after all the deductions are removed is 450 - 150 - 36 - 50 - 20 - 10 = 184 dollars.
The answer: 184

Question: Bobby received his weekly paycheck today. Although his salary is $450 per week, his actual paycheck is reduced in size because there are some taxes, insurance payments, and fees removed from his pay before his employer writes the check. If the government removes 1/3 in federal taxes and 8% in state taxes, the health insurance removes $50 per week, the life insurance removes $20 per week, and the city charges him a fee of $10 per week for parking, then what is the final amount left in Bobby's paycheck, in dollars?
The total cost of toilet paper is 10 * $1.5 = $15. The total cost of paper towels is 7 * $2 = $14. The total cost of tissues is $35 - $15 - $14 = $6. The cost of one box of tissues is $6 / 3 = $2.
The answer: 2
Reverse engineering the question: Amber goes to the store and buys 10 rolls of toilet paper, 7 rolls of paper towels, and 3 boxes of tissues. One roll of toilet paper costs $1.50. One roll of paper towels costs $2. If the total cost of all the items is $35, how much does one box of tissues cost?
Reasoning and answer: The region of plain A has a total of 200 - 50 = 150 square miles. The total number of square miles for both plains is 150 square miles for plain A + 200 square miles for plain B = 350 square miles.
The answer: 350

Question: The region east of plain A is 50 square miles less than the region east of plain B. If plain B has 200 square miles, how many square miles do the plains have in total?
Reasoning and answer: Two pairs of sunglasses costs 2 x $50 = $100. So, Mary spent $100 + $100 = $200. Thus, two decks of basketball cards costs $200 - $150 = $50. Therefore, one deck of basketball cards costs $50 / 2 = $25.
The answer: 25
