[Question]If Clover goes for a 1.5-mile walk in the morning and another 1.5-mile walk in the evening, every day, how many miles does he walk in 30 days?
[Answer]He walks 1.5 miles in the morning and 1.5 miles in the evening so that’s 1.5 + 1.5 = 3 miles. If he walks 3 miles everyday, for 30 days then he walks 3 * 30 = 90 miles in 30 days. The answer is 90.

[Question]Steve owns a lake shop that sells fish. He has a stock of 200 fish. He sells 50 fish and because his refrigerators stop working a third of the remaining fish become spoiled. A new stock of 200 more fish arrives. How many fish does he have in stock now?
[Answer]If he had 200 fish and sells 50, he is left with 200 - 50 = 150 fish. If a third of them get spoiled 1 / 3 * 150 = 50 fish get spoiled. The remaining number of fish is now 150 - 50 = 100. He then gets 200 more to make 100 + 200 = 300 fish. The answer is 300.

[Question]Darren bought 4 boxes of crackers. Each box contained 24 crackers. If Calvin bought one box less than twice as many boxes of crackers as Darren, how many crackers did they buy altogether?
[Answer]If Darren bought 4 boxes of crackers, each containing 24 crackers, the total number of crackers that Darren bought is 24 * 4 = 96. Twice as many boxes of crackers as Darren bought is 2 * 4 = 8. If Calvin bought one box less than twice as many boxes of crackers as Darren, then Calvin bought 8 - 1 = 7 boxes of crackers. The total number of crackers that Calvin bought is 7 * 24 = 168. Together, Darren and Clavin bought 168 + 96 = 264 crackers. The answer is 264.

They get 2 15 minute breaks a day so that’s 2 * 15 = 30 minutes. They get 30 minutes for lunch and 20 minutes for recess plus an additional 30 minutes of recess for a total of 30 + 20 + 30 = 80 minutes spent outside of class. The answer is 80.
