Question: John invests in a bank and gets 10% simple interest. He invests $1000. How much money does he have after 3 years?
Answer: He gets 1000 * .1 = $100 a year. So after 3 years, he gets 100 * 3 = $300. So he has 300 + 1000 = $1300. The answer is 1300.
[Question]The government gives the bottom 20% of people a $2000 stimulus. They have found that this kind of stimulus returns 5 times as much money to the government, in terms of tax revenue, as it cost. The city has 1000 people in it. What was the government profit from this project?
[Answer]They gave money to 1000 * .2 = 200 people. It cost 200 * 2000 = $400,000. There was a 5 to 1 return so the government collected 5 * 400000 = $2,000,000. That means the profit was 2,000,000 - 400,000 = $1,600,000. The answer is 1600000.
Q: The ratio of the amount of money Cara, Janet, and Jerry have is 4:5:6. If the total amount of money they have is $75, calculate the loss Cara and Janet will make if they combine their money to buy oranges and sell them at 80% of the buying price.
A: The sum of the ratios representing the amount of money the three has is 4 + 5 + 6 = 15. If the total amount of money they have is $75, the amount of money Cara has represented by the fraction 4 / 15 is 4 / 15 * $75 = $20. Similarly, the amount of money Janet has represented by the fraction 5 / 15 of the total ratio is 5 / 15 * $75 = $25. Combined, Cara and Janet have $20 + 25 = $45. If Cara and Janet buy goods worth $45 and sells them at 80% of the buying price, the selling price of the goods will be 80 / 100 * $45 = $36. Since they bought the goods at $45 and sold them at $36, Janet and Cara would run at a loss of $45 - $36 = $9. The answer is 9.

[Question]Blake gave some of his money to his friend, Connie. Connie used all the money she had been given to buy some land. In one year, the land tripled in value. So, she sold the land and gave half of all the money she got from the sale of the land to Blake. If Connie gave Blake $30,000, how much money, in dollars, did Blake initially give to Connie?
[Answer]If half the value of what Connie sold the land for was $30,000, then the full value was $30,000 * 2 = $60,000. If $60,000 is triple what Connie bought the land for, then the initial cost, which is the amount given to her by Blake, was $60,000 / 3 = $20,000. The answer is 20000.
[Question]Pearl wants to order 5 monogrammed Christmas stockings for each of her 5 grandchildren and her own 4 children. The stockings are $20.00 each and currently 10% off. The monogramming will costs $5.00 per stocking. How much will the stockings costs?
[Answer]
She has 5 grandchildren 4 children so she needs 5 + 4 = 9 stockings. The stockings are $20.00 each and currently 10% off so that's 20 * .10 = $2.00 off. The stockings are $20.00 with a $2.00 discount so they are each 20 - 2 = $18.00. The stockings are now $18.00 and she needs 9 so that's $162.00. She also wants to monogram each stocking at $5.00 per stocking so that's 9 * 5 = $45.00. The stockings are $162.00 and the monogramming will cost $45.00 so the stockings will cost 162 + 45 = $207.00. The answer is 1035.
