[Question]Tom Sawyer has tricked his friends into whitewashing Aunt Polly's 100-foot fence. His first friend, Ben, whitewashed 10 feet. His second friend Billy whitewashed a fifth of the remaining fence. A third friend, Johnny, whitewashed a third of the fence that was left after that. How much of the fence still needs to be whitewashed?
[Answer]It's a 100 - foot fence, and Ben whitewashed 10 feet, so there are 100 - 10 = 90 feet left after Ben is done. Billy whitewashed a fifth of that, or 90 / 5 = 18 feet. There is now 90 - 18 = 72 feet of fence left. Johnny whitewashes a third of that, or 72 / 3 = 24 feet. That leaves 72 - 24 = 48 feet of fence left to be whitewashed. The answer is 48.
Q: John works a job that offers performance bonuses. He makes $80 a day and works for 8 hours. He has the option of working hard to earn the performance bonus of an extra $20 a day, but the extra effort results in a 2-hour longer workday. How much does John make per hour if he decides to earn the bonus?
A: First, we need to determine the length of John's workday if he decides to earn the bonus. We do this by performing 8 + 2 = 10 hours for his workday. Next, we need to determine his overall pay. We do this by performing 80 + 20 = 100 dollars a day. We then determine John's hourly rate by dividing his pay by the number of hours worked, performing 100 / 10 = 10 dollars an hour. The answer is 10.
Question: At a gym, the blue weights are 2 pounds each, and the green weights are 3 pounds each. Harry put 4 blue weights and 5 green weights onto a metal bar. The bar itself weighs 2 pounds. What is the total amount of weight, in pounds, of Harry's custom creation?
Answer: The blue weights weigh 4 * 2 = 8 pounds. The green weights weigh 5 * 3 = 15 pounds. The weights weigh 8 + 15 = 23 pounds. The total is then 23 + 2 = 25. The answer is 25.
[Question]In his company, Kenzo has 80 office chairs with five legs each and 20 round tables with three legs each. If after a month 40% of the chairs are damaged and have to be disposed of, calculate the total number of legs of furniture Kenzo has remaining in his company.
[Answer]The number of chairs that are disposed of after they're found to be damaged is 40 / 100 * 80 = 32. The number of chairs in good condition in Kenzo's company is 80 - 32 = 48. The 48 chairs have 48 * 5 = 240 legs. The round tables also have 20 * 3 = 60 legs. In total, the furniture in Kenzo's company has 60 + 240 = 300 legs. The answer is 300.
Q: Carla is making smoothies. If she uses 500 ml of watermelon puree and 100 ml of cream, how many 150 ml servings can she make?
A: First find the total volume of the smoothie mix: 500 ml + 100 ml = 600 ml. Then divide the total volume by the volume per serving to find the number of servings: 600 ml / 150 ml / serving = 4 servings. The answer is 4.
Question: On Monday Samson ate 3 sandwiches at lunch and ate twice as many at dinner. The next morning, he felt sick from eating all those sandwiches, so he only ate one sandwich for breakfast. How many more sandwiches in total did Samson eat on Monday than Tuesday?
Answer:
Samson ate 3 sandwiches x 2 = 6 sandwiches at dinner on Monday. He ate 3 sandwiches + 6 sandwiches = 9 sandwiches total on Monday. Therefore, he ate 9 sandwiches - 1 sandwich = 8 more sandwiches on Monday than Tuesday. The answer is 8.
