[Question]Frank went to a shop to buy some food for his breakfast. He bought 10 buns for $0.1 each, two bottles of milk, for $2 each, and a carton of eggs, which was three times more expensive than one bottle of milk. How much did Frank pay for his breakfast shopping?
[Answer]For the buns, Frank paid 10 * 0.1 = $1. He bought two bottles of milk, for $2 each, so he paid for them 2 * 2 = $4. One carton of eggs was three times more expensive than one bottle of milk, so it cost 3 * 2 = $6. So for all his shopping Frank had to pay 1 + 4 + 6 = $11. The answer is 11.
Q: A store marks a book 30% above the cost. But during a sale, a 10% discount was given. If the book costs $50, what is the percent profit?
A: The store made a $50 x 30 / 100 = $15 profit for selling it 30% above the cost. So, the book was sold for $50 + $15 = $65. During a sale, the book’s selling price decreased by $65 x 10 / 100 = $6.50. So, the book was sold for $65 - $6.50 = $58.50. There was $58.50 - $50 = $8.50 profit after the discount. Therefore, the percent profit is $8.50 / $50 x 100% = 17%. The answer is 17.
Question: At a laundromat, it costs $4 for a washer and a quarter for every 10 minutes in the dryer. Samantha does 2 loads of laundry in the wash and then divides all the washed clothes equally into 3 separate dryers. If she lets the dryers run for 40 minutes each, how much does she spend altogether?
Answer: Samantha spends $4 x 2 = $8 on washing. Each dryer costs 25 x 4 = 100 cents = $1. Three dryers cost 1 x 3 = $3. Altogether, she spends 8 + 3 = $11. The answer is 11.
[Question]The number of soldiers on opposite sides of a war each needs 10 pounds of food every day to continue fighting effectively. However, soldiers in the second are each given 2 pounds less food than the first side. If the first side has 4000 soldiers and the other side 500 soldiers fewer than the first side, what's the total amount of pounds of food both sides are eating altogether every day?
[Answer]The first side with 4000 soldiers is eating 4000 * 10 = 40000 pounds of food every day. Since the other side has 500 soldiers fewer than the first side, there are 4000 - 500 = 3500 soldiers on the second side. Soldiers on the second side are each given 10 - 2 = 8 pounds of food. The total amount of food the second side eats is 8 * 3500 = 28000. Altogether, the two sides eat 28000 + 40000 = 68000 pounds of food every day. The answer is 68000.
Q: A park has 50 benches with a capacity of 4 people each. On a Sunday afternoon, 80 people were sitting on the benches. What's the number of available spaces on the benches that other people can sit on before the carrying capacity of the benches is full?
A: In the park, 50 benches with a capacity of four people each have a total capacity of 50 * 4 = 200 sitting spaces. If 80 people are already using spaces, the number of empty spaces is 200 - 80 = 120. The answer is 120.
Question: Jack goes up three flights of stairs, then down six flights of stairs. If each flight of stairs has 12 steps that each each 8 inches high, how many feet further down is Jack than when he started?
Answer:
First find the number of inches in each flight of stairs: 12 steps * 8 inches / step = 96 inches. Then find the net number of flights of stairs Jack went down: 6 flights - 3 flights = 3 flights. Then multiply than number by the number of inches per flight to find how many inches further down he is: 96 inches / flight * 3 flights = 288 inches. Then divide that number by 12 to find the number of feet down he is: 288 inches / 12 inches / foot = 24 feet. The answer is 24.
