Question: Oliver had 135 stickers. He used 1/3 of his stickers, gave 2/5 of the remaining to his friend, and kept the remaining stickers. How many stickers did he keep?
Answer: Step-by-step reasoning process: Oliver used 1 / 3 x 135 = 45 stickers. So, there were 135 - 45 = 90 stickers remaining. His friend received 2 / 5 x 90 = 36 stickers. Therefore, Oliver kept 90 - 36 = 54 stickers.
So the answer is 54.

Question: Tom Brady is shy of the passing yards record in a season. The current record is 5999 yards. He currently has 4200 yards with 6 games left in the season. How many passing yards per game does he need to average to beat the record?
Answer: Step-by-step reasoning process: Tom needs to pass for 6000 - 4200 = 1800 yards to beat the record. Therefore, he needs to average 1800 yards / 6 games = 300 yards per game.
So the answer is 300.

Question: Jenny's property tax rate is 2%. Her house is currently worth $400,000. The city is about to build a new high-speed rail project nearby, which will increase her house's value by 25%. Jenny can only afford to spend $15,000/year on property tax. How many dollars worth of improvements can she make to her house before her property tax bill gets too high?
Answer: Step-by-step reasoning process: First find how much the rail project will increase the house value by multiplying the initial value by 25%: $400,000 * .25 = $100,000. Then add that amount to the initial value to find the new value: $100,000 + $400,000 = $500,000. Then divide the maximum amount of property tax Jenny can afford to pay by the property tax rate to find the maximum value her house can have: $15,000 / .02 = $750,000. Now subtract the house's value after the rail project from the maximum value to find how much value the improvements can have: $750,000 - $500,000 = $250,000.
So the answer is 250000.

Question: In a single day, it rained for many hours. From 2pm to 4pm, it rained at a rate of 4 inches per hour. From 4pm to 7pm, it rained at a rate of 3 inches per hour. And from 7pm to 9pm, it rained at a rate of 0.5 inches per hour. If the rain gauge started out the day already containing 2 inches of rainwater, how many inches of water will the gauge contain at 9pm?
Answer:
Step-by-step reasoning process: From 2pm to 4pm is 4 - 2 = 2 hours. Thus, from 2 - 4pm, raining at 4 inches per hour, it added 8 inches to the rain gauge. From 4pm to 7pm is 7 - 4 = 3 hours. Thus, from 4 - 7pm, raining at a rate of 3 inches per hour, it added 3 * 3 = 9 inches to the rain gauge. From 7pm to 9pm is 9 - 7 = 2 hours. Thus, from 7 - 9pm, raining at a rate of 0.5 inches per hour, it added 2 * 0.5 = 1 inch to the gauge. If the gauge originally contained 2 inches of water, by 9pm the gauge contained 2 + 8 + 9 + 1 = 20 inches of water.
So the answer is 20.
