Reasoning and answer: On the second day, he collected 3 times the number of tins he collected on the first day, which is 3 * 50 = 150 tins. On the third day, he collected 50 tins fewer than the second day, which is 150 - 50 = 100 tins. The total for the three days is 150 + 100 + 50 = 300 tins. To reach his goal, he still needs 500 - 300 = 200 tins. Since the total number of days left in the week is 4, he'll need to collect 200 / 4 = 50 tins per day to reach his goal.
The answer: 50

Question: James decides to build a tin house by collecting 500 tins in a week. On the first day, he collects 50 tins. On the second day, he manages to collect 3 times that number. On the third day, he collects 50 tins fewer than the number he collected on the second day. If he collects an equal number of tins on the remaining days of the week, what's the number of tins he collected each day for the rest of the week?


First find the total number of snakes eaten: 5 snakes / jaguar * 6 jaguars = 30 snakes. Then find the total number of birds eaten per day: 30 snakes * 3 birds / snake = 90 snakes. Then multiply the number of snakes by the number of beetles per snake to find the total number of beetles eaten per day: 90 snakes * 12 beetles / snake = 1080 beetles.
The answer: 1080
Reverse engineering the question: Each bird eats 12 beetles per day, each snake eats 3 birds per day, and each jaguar eats 5 snakes per day. If there are 6 jaguars in a forest, how many beetles are eaten each day?

Jimmy spent 3 * $1 = $3 on pens. He spent 4 * $3 = $12 on notebooks. He spent 2 * $5 = $10 on folders. He spent $3 + $12 + $10 = $25 in total. His change will be $50 - $25 = $25.
The answer: 25
Reverse engineering the question: Jimmy bought 3 pens for school for $1 each, 4 notebooks for $3 each and 2 folders for $5 each. If he paid with a $50 bill, how much change will he get back?


Reasoning and answer: On Tuesday Matt worked 450 minutes / 2 = 225 minutes. On Wednesday Matt worked 300 minutes - 225 minutes = 75 minutes more.
