Question: Nancy carves statues out of jade. A giraffe statue takes 120 grams of jade and sells for $150. An elephant statue takes twice as much jade and sells for $350. If Nancy has 1920 grams of jade, how much more money will she make turning it all into elephants instead of giraffes?
Answer: First find how many giraffe statues Nancy can make by dividing the total amount of jade by the amount used per giraffe statue: 1920 g / 120 g / giraffe = 16 giraffes. Then multiply that number by the price per giraffe to find how much Nancy earns total from giraffes: 16 giraffes * $150 / giraffe = $2400. Then find how much jade each elephant statue uses by doubling the jade used by the giraffe statues: 120 g / giraffe * 2 = 240 g / elephant. Then find how many elephant statues Nancy can make by dividing the total amount of jade by the amount used per elephant statue: 1920 g / 240 g / elephant = 8 elephant. Multiply that number by the price per elephant to find Nancy's total earnings from elephants: 8 elephants * $350 / elephant = $2800. Finally, subtract Nancy's total earnings from the giraffes from her total earnings from the elephants to find the difference: $2800 - $2400 = $400. The answer is 400.

Question: Mr. John works at a shopping mall and receives a monthly income of $2000, but he spends approximately 5% of this amount on public transport to and from the mall in a month. How much will he have left after deducting his monthly transport fare from his income?
Answer: 5% of $2000 is (5 / 100) * $2000 = $100. After removing his transport fare, he will have $2000 - $100 = $1900 left. The answer is 1900.

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?
Answer: 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 is 10.

Question: Mary and Jimmy start running from the same spot, but in opposite directions. Mary runs at 5 miles per hour and Jimmy runs at 4 miles per hour. What is the distance between them after 1 hour?
Answer:
In 1 hour, Mary will have traveled 5 miles / hour * 1 hour = 5 miles. In 1 hour, Jimmy will have traveled 4 miles / hour * 1 hour = 4 miles. Since they are running in opposite directions, the distance between them will be 5 miles + 4 miles = 9 miles. The answer is 9.
