Q: Corna wants to buy a shirt. The store buys the shirt for $20, but charges 30% for profit. However, the shirt is on sale for 50% off the selling price. What is the price now?
A: First find how much the store makes in profit: $20 * 0.30 = $6 for profit. Then find the regular selling price: $20 + $6 = $26 total price. Then multiply the regular price by the discount to get $26 * 0.50 = $13 for the final price. The answer is 13.
Question: Tom is binge-watching a show on Netflix. The show has 90 episodes, each one of which is 20 minutes long because there are no commercials. If Tom can spend two hours a day watching the show, how many days will it take him to finish watching the show?
Answer: Each episode is 20 minutes long, and there are 90 episodes, so the series takes 20 minutes per episode * 90 episodes = 1800 minutes to watch. 1800 minutes / 60 minutes per hour = 30 hours to watch the series. Tom can watch 2 hours of TV a day, so it will take him 30 hours / 2 hours per day = 15 days to watch the entire series. The answer is 15.
[Question]Katy participated in a summer reading program at her local library. She read 8 books in June, twice as many in July and three fewer in August than she did in July. How many books did Katy read during the summer?
[Answer]Katy read twice as many books in July as she did in June, so she read 2 * 8 = 16 books in July. She read three fewer books in August than she did in July, so she read 16 - 3 = 13 books in August. So, including June, she read 8 + 16 + 13 = 37 books total. The answer is 37.
Q: Linda's bag has 2 dimes, 6 quarters, and 5 nickels. Her mother gives her 2 more dimes, 10 quarters, and twice as many nickels as she has. How many coins does she have altogether?
A: When Linda's mother gave her 2 more dimes, the total number of dimes increased to 2 + 2 = 4 dimes. She also increased the total number of quarters to 6 + 10 = 16 after her mother gave her 10 more. The total number of dimes and quarters she has is 16 + 4 = 20. Linda's mother also gave her twice as many nickels as she has, a total of 2 * 5 = 10 nickels. The total number of nickels she has increased to 10 + 5 = 15. Altogether, Linda has 20 + 15 = 35 coins. The answer is 35.
Question: Will's mom gave him $74 to go shopping. He bought a sweater for $9, a T-shirt for $11 and a pair of shoes for $30. He then returned his shoes for a 90% refund. How much money does Will have left?
Answer: Will paid $30 for his shoes but then returned them and got 90% of the money back, so he lost 10% of the money, which means 10 / 100 * $30 = $3 is gone. Will spent $9 + $11 + $3 = $23. Will started with $74 - $23 that he spent = $51 remaining. The answer is 51.
Q: Legoland has 5 kangaroos for each koala. If Legoland has 180 kangaroos, how many koalas and kangaroos are there altogether?
