Q: A house’s living room, dining room and kitchen take up 1,000 sq ft. The house also has a guest bedroom and a master bedroom suite. If the guest bedroom is a quarter of the size of the master bedroom suite, and the house is 2,300 sq ft total, how large is the master bedroom suite?
A: The house is 2,300 sq ft and we know the non - bedroom sections take up 1,000 sq ft, so that leaves 2300 - 1000 = 1,300 sq ft for the bedrooms / bathrooms. Let x be the size of the master bedroom suite. Then the guest bedroom is 0.25x. So together the bedrooms are x + 0.25x = 1.25x in size. This means 1.25x = 1300. So x = 1300 / 1.25 = 1040 sq ft. The answer is 1040.
Question: Lidia bought a new tablet, and she needs to buy some apps for it. One app costs $4 on average, and Lidia needs 15 of them. She has $66 for this purpose. How much money will she be left with if she buys all the apps she needs?
Answer: So Lidia will spend 4 * 15 = $60 on apps. She already has $66, so she will be left with 66 - 60 = $6. The answer is 6.
[Question]Dianne runs a store that sells books. 37% of her 1000 customers end up returning their books. Her books all cost 15 dollars apiece. How much money does she keep in sales after subtracting the returns?
[Answer]Diane made 1000 * 15 = $15000 in sales because she had 1000 customers each buy a $15 book. 37% of those customers returned their books, so that means she had .37 * 1000 = 370 returns. Each of those returns was for a $15 book, so she had 370 * 15 = $5,550 in returns. For her total leftover income, we subtract the returns from the sales and end up with 15000 - 5550 = $9450 in income. The answer is 9450.
Q: Willie came back from Europe with 70 euros. Normally 5 euros is worth 1 dollar, but the money exchange at the airport will only give Willie 5/7ths of the official exchange rate. How many dollars does Willie get?
A: First first out how many euros Willie should have gotten using the official exchange rate: 70 euros / 5 euros / dollar = $14. Then multiply this quantity by 5 / 7 to find how many dollars he actually got: 14 dollars * 5 / 7 = $2 * 5 = $10. The answer is 10.
Question: To make yogurt, the company needs milk and fruit. Milk is bought at $1.5 per liter and fruit at $2 per kilogram. To make one batch of yogurt, the company needs 10 liters of milk, and 3 kilograms of fruit. How much does it cost the firm to produce three batches of yogurt?
Answer: For the fruits, the company needs to pay 3 * 2 = $6 per batch. 10 liters of milk is a cost of 10 * 1.5 = $15 for the company. So in total one batch is a cost of 15 + 6 = $21. So three batches of yogurt is a cost of 3 * 21 = $63. The answer is 63.
Q: The company's data entry team had 5 employees working on a large project. Rudy types 64 words per minute, Joyce types 76 words per minute, Gladys types 91 words per minute, Lisa types 80 words per minute and Mike types 89 words per minute. What is the team's average typed words per minute?
A:
Rudy types 64, Joyce types 76, Gladys types 91, Lisa types 80 and Mike types 89 so 64 + 76 + 91 + 80 + 89 = 400. There are 5 team members, so they type at an average speed of 400 / 5 = 80 words per minute. The answer is 80.
