question:A craft store makes a third of its sales in the fabric section, a quarter of its sales in the jewelry section, and the rest in the stationery section. They made x sales today. How many sales were in the stationery section? If we know the answer to the above question is 15, what is the value of unknown variable x?
answer:The craft store makes a third of its sales in the fabric section, which means it makes (1/3)*x sales in the fabric section. It also makes a quarter of its sales in the jewelry section, which means it makes (1/4)*x sales in the jewelry section. The total number of sales in the stationery section is the remaining sales after accounting for the fabric and jewelry sections: x - ((1/3)*x + (1/4)*x) = x - (4/12)*x - (3/12)*x = x - (7/12)*x. We are given that the number of sales in the stationery section is 15, so we can write: x - (7/12)*x = 15. Simplifying the left side, we get: (12/12)*x - (7/12)*x = (5/12)*x = 15. Multiplying both sides by 12/5, we get: x = (12/5)*15 = 36. The value of x is 36. 36 The answer is: 36
question:The average score on last week's Spanish test was 90. Marco scored 10% less than the average test score and Margaret received 5 more points than Marco. What score did Margaret receive on her test?
answer:If the average test score was 90, and Marco scored 10% less than the average, then Marco scored 90 - (10/100) * 90 = 90 - 9 = 81. If Margaret received 5 more points than Marco, then Margaret received 81 + 5 = 86 on her test. 86 The answer is: 86
question:order to go on a trip to Brickville, Jacoby needs a total of 5000. He earns 20 per hour and works for 10 hours. He also sells cookies for 4 each and sells a total of 24 cookies. With the money he has earned, he buys a lottery ticket for 10 and wins 500. Additionally, he receives 500 as a gift from each of his sisters. How much more money, in dollars, does Jacoby need to afford the trip to Brickville?
answer:Jacoby earns 20 per hour and works for 10 hours, so he earns 20 * 10 = 200. He also sells cookies for 4 each and sells a total of 24 cookies, so he earns 4 * 24 = 96 from selling cookies. With the money he has earned, he has a total of 200 + 96 = 296. He buys a lottery ticket for 10 and wins 500, so he now has 296 - 10 + 500 = 786. He also receives 500 as a gift from each of his sisters, so he now has 786 + 500 + 500 = 1786. In order to afford the trip to Brickville, Jacoby needs a total of 5000, so he still needs 5000 - 1786 = 3214. 3214 The answer is: 3214
