Question: Thomas buys a weight vest. It weighed 60 pounds and worked well for him in the beginning but after a bit of training he decides he wants to increase the weight by 60%. The weights come in 2-pound steel ingots. Each ingot cost $5 and if you buy more than 10 you get a 20% discount. How much does it cost to get the weight he needs?
Answer: He needs to buy 60 * .6 = 36 pounds. So he needs to buy 36 / 2 = 18 weight plates. That would cost 18 * 5 = $90. Since he bought more than 10 he gets a discount so he gets 90 * .2 = $18 off. That means he paid 90 - 18 = $72. The answer is 72.
[Question]Mike decides to develop a plot of land. He bought 200 acres for $70 per acre. After development, he sold half of the acreage for $200 per acre. How much profit did he make?
[Answer]He bought the land for 200 * 70 = $14000. He sold 200 / 2 = 100 acres. He got 100 * 200 = $20,000 from selling this. So he made a profit of 20,000 - 14,000 = $6,000. The answer is 6000.
Q: Martha receives a daily allowance of $12. She decides to save half of this amount every day. In the first week she kept her commitment with the exception of one day when she saved only a quarter of this amount. How much has she saved at the end of this week?
A: Half of $12 is (1 / 2) * $12 = $6. There are 7 days in a week so if she saved half every day except one then she saved half for 7 - 1 = 6 days. She saved $6 for 6 days for a total of $36. A quarter of $12 is (1 / 4) * $12 = $3. She saved a quarter once for a total savings of $3 + $36 = $39. The answer is 39.
Question: All people named Barry are nice, while only half of the people named Kevin are nice. Three-fourths of people named Julie are nice, while 10% of people named Joe are nice. If a crowd contains 24 people named Barry, 20 people named Kevin, 80 people named Julie, and 50 people named Joe, how many nice people are in the crowd?
Answer: If all people named Barry are nice, and the crowd contains 24 people named Barry, then 1 * 24 = 24 of these people are nice. If only half of people named Kevin are nice, and the crowd contains 20 people named Kevin, then 0.5 * 20 = 10 of these people are nice. If three - fourths of people named Julie are nice, and the crowd contains 80 people named Julie, then (3 / 4) * 80 = 60 of these people are nice. If 10% of people named Joe are nice, and the crowd contains 50 people named Joe, then 0.1 * 50 = 5 of these people are nice. In total, the crowd contains 24 + 10 + 60 + 5 = 99 people who are nice. The answer is 99.
[Question]A normal lemon tree produces 60 lemons per year. Jim has specially engineered lemon trees that produce 50% more lemons per year. He has a grove that is 50 trees by 30 trees. How many lemons does he produce in 5 years?
[Answer]Each tree produces 60 * .5 = 30 more lemons than normal. So they each produce 60 + 30 = 90 lemons. He has 50 * 30 = 1500 trees. So every year he produces 1500 * 90 = 135000 lemons. That means he produces 135000 * 5 = 675,000. The answer is 675000.
