Q: 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?
A: 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.
Question: Jack went to a supermarket with $100 and bought 4 bottles of water. Then his mother called him and asked him to buy twice as many bottles as he already bought. Each bottle cost $2. Finally, he also bought half a pound of cheese and 1 pound of cheese costs $10. How much money does Jack have remaining?
Answer: Jack's mother asked him to buy 2 * 4 = 8 bottles of water. Thus Jack bought 4 + 8 = 12 bottles of water in total. Altogether, the bottles of water cost 12 * $2 = $24. The cheese cost 1 / 2 * $10 = $5. So Jack spent $24 + $5 = $29 on water and cheese. Since he started with $100, he now has $100 - $29 = $71 left. The answer is 71.
