[Question]Dennis wants to buy 4 pairs of pants from the store which cost $110.00 each with a 30% discount and he also wants to buy 2 pairs of socks which cost $60.00 with a 30% discount. How much money will Dennis have to spend in total after he bought all the items he wants after the discount?
[Answer]Dennis wants to buy 4 pairs of pants which cost 110x4 = $440. And he also wants to buy 2 pairs of socks that cost 60x2 = $120. The total amount he needs to spend without the discount is 440 + 120 = $560. The discount he will have amounts to $560x.0.30 = $168.00. So the total amount he needs to spend after deducting the discount from the total amount is 560 - 168 = $392. The answer is 392.
Q: Elisa and her two friends went out to dinner. Each of them ordered a meal worth $10. Afterwards, they each had a scoop of the same kind of ice cream. If the $45 Elisa had was enough to pay for everything, what was the cost of a scoop of ice cream?
A: The three friends had meals worth 10 * 3 = 30 dollars. If they paid for the meals only, they would have remained with 45 - 30 = 15 dollars. Dividing the remaining amount by the number of ice cream scoops gives 15 / 3 = 5 dollars. Each scoop of ice cream cost 5 dollars. The answer is 5.
Question: Daniel collects Russian dolls that normally cost $4 each. He saves enough money to buy 15 Russian dolls. However, the price suddenly drops to $3 each. How many Russian dolls can he buy now at the discounted price, given his savings?
Answer: With the price of each doll at $4, this means he has saved a total of 15 * 4 = $60. When the price is lowered to $3 each, he can now purchase 60 / 3 = 20 dolls. The answer is 20.
[Question]To buy a book, you pay $20 for each of the first 5 books at the supermarket, and for each additional book you buy over $20, you receive a discount of $2. If Beatrice bought 20 books, how much did she pay at the supermarket?
[Answer]For the first five books, the total cost is $20 * 5 = $100. For every additional book over $5, you pay $2 less, totaling to $20 - $2 = $18. Beatrice bought 20 books, so the number of books at which she received the $2 discount is 20 - 5 = 15 books. For the 15 books, Beatrice paid 15 * $18 = $270. In total, Beatrice paid $100 + $270 = $370 for the 20 books. The answer is 370.
Q: Celia runs twice as fast as Lexie. If it takes Lexie 20 minutes to run a mile, how long, in minutes, will it take Celia to 30 miles?
A: If Lexie takes 20 minutes to run a mile, Celia takes 20 / 2 = 10 minutes to run the same distance since she is twice as fast. Celia takes 10 minutes to run one mile so it will take 10 * 30 = 300 minutes to run 30 miles. The answer is 300.
Question: Mrs. Lim milks her cows twice a day. Yesterday morning, she got 68 gallons of milk and in the evening, she got 82 gallons. This morning, she got 18 gallons fewer than she had yesterday morning. After selling some gallons of milk in the afternoon, Mrs. Lim has only 24 gallons left. How much was her revenue for the milk if each gallon costs $3.50?
Answer:
Mrs. Lim got 68 gallons - 18 gallons = 50 gallons this morning. So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = 200 gallons. She was able to sell 200 gallons - 24 gallons = 176 gallons. Thus, her total revenue for the milk is $3.50 / gallon x 176 gallons = $616. The answer is 616.
