It cost 100,000 * .01 = $1,000 a day to keep the place open. He makes 150 * 10 = $1500 a day from the park. So he makes a profit of 1500 - 1000 = $500 a day. So it takes 100000 / 500 = 200 days to make back his money.
The answer: 200
Reverse engineering the question: Tom opens an amusement park. It cost $100,000 to open initially. It also cost 1% of that to run per day. He sells 150 tickets a day for $10 each. How long will it take to make back his money?


Reasoning and answer: First figure out how much the first babysitter costs by multiplying her hourly rate by the number of hours she works: $16 / hour * 6 hours = $96. Then use the same method to figure out how much the second babysitter charges before any screaming: $12 / hour * 6 hours = $72. Then figure out how much the babysitter charges for two screams: 2 screams * $3 / scream = $6. Finally, subtract the second babysitter's two charges from the first babysitter's total charge to find the difference: $96 - $72 - $6 = $18.
The answer: 18

Question: Milly's babysitter charges $16/hour. Milly is considering switching to a new babysitter who charges $12/hour, but also charges an extra $3 for each time the kids scream at her. If Milly usually hires the babysitter for 6 hours, and her kids usually scream twice per babysitting gig, how much less will the new babysitter cost?


Each episode takes 20 * .5 = 10 minutes longer to film than it is. So it takes 20 + 10 = 30 minutes. They are filming 5 * 4 = 20 episodes. So it takes 20 * 30 = 600 minutes. This is equivalent to 600 / 60 = 10 hours.
The answer: 10
Reverse engineering the question: Tim host a show and they film multiple episodes per day. Each episode is 20 minutes long and it takes 50% longer than that to film each episode. Each week they show 5 episodes. How many hours would it take to film 4 weeks of episodes?


Reasoning and answer: Tom will be 30 in 5 years so now he is 30 - 5 = 25. 2 years ago Tom was 25 - 2 = 23. At that time, Jared was twice as old as Tom so Jared was 23 * 2 = 46. Two years have since passed so Jared is now 46 + 2 = 48.
The answer: 48
What was the question?
Question: Two years ago, Jared was twice as old as Tom. If Tom will be 30 in five years, how old is Jared now?


Owen bought 12 boxes for a total of $9 / box x 12 boxes = $108. Six boxes contains 6 boxes x 50 masks / box = 300 face masks. Owen made 300 masks / 25 masks / repack = 12 repacks. So, his revenue for selling those repacked face masks is $5 x 12 repacks = $60. There are 300 masks / 10 masks / baggy = 30 baggies face masks. So, his revenue for that is $3 / baggy x 30 baggies = $90. Hence, his total revenue for all the face masks is $60 + $90 = $150. This gives him a profit of $150 - $108 = $42.
The answer: 42
Reverse engineering the question: Owen bought 12 boxes of face masks that cost $9 per box. Each box has 50 pieces of masks. He repacked 6 of these boxes and sold them for $5 per 25 pieces. He sold the remaining 300 face masks in baggies at the rate of 10 pieces of mask for $3. How much profit did he make?


Tom can buy 1000 / 2 = 500 for half price. He will spend $.50 / 2 = $.25 on the half - priced bricks. Thus, he will spend 500 * $.25 = $125 on the half - priced bricks. He will spend 500 * $.50 = $250 on the full - priced bricks. Thus, he will spend $125 + $250 = $375 total.
The answer: 375
Reverse engineering the question:
To make a shed in his backyard, Tom needs 1000 bricks. He can buy half of the bricks for 50% off of $.50. The other Half he needs to pay full price. How many dollars does Tom spend?
