Q: Alice had 10 dozens of watermelons. She sold 40% of it yesterday and 1/4 of the remaining today, How many watermelons are left to be sold tomorrow?
A: Ten dozens of watermelons are equal to 10 x 12 = 120 watermelons. Yesterday, Alice sold 120 x 40 / 100 = 48 watermelons. So, there are only 120 - 48 = 72 watermelons left for today. Today, Alice sold 72 x 1 / 4 = 18 watermelons. Hence, 72 - 18 = 54 watermelons are left to be sold tomorrow. The answer is 54.
Question: Connie redeemed all her arcade tickets today. She spent half of them on a stuffed koala bear. She spent 10 tickets on a pair of earbuds. She spent another 15 tickets on glow bracelets. How many tickets did Connie redeem today?
Answer: Connie spent 10 tickets on earbuds + 15 tickets on glow bracelets = 25 tickets. Since Connie spends half of her tickets on a stuffed koala bear, that means the 25 tickets she spent on earbuds and glow bracelets is the other half, so she spent 25 tickets on the stuffed koala bear. In all, Connie spent 25 tickets on earbuds and glow bracelets + 25 tickets on a stuffed koala bear = 50 tickets. The answer is 50.
[Question]Jackson wants to impress his girlfriend by filling her hot tub with champagne. The hot tub holds 40 gallons of liquid. Each bottle of champagne holds 1 quart. (There are 4 quarts per gallon). If each bottle of champagne costs $50, but Jackson gets a 20% volume discount, how much does he spend on champagne?
[Answer]First find the number of quarts the hot tub holds by multiplying the number of gallons it holds by 4: 40 gallons * 4 quarts / gallon = 160 quarts. Then multiply the number of quarts of champagne Jackson buy by the normal price per bottle to find the cost before the discount: 160 quarts * $50 / quart = $8000. Then multiply that number by 20% to find the amount of the discount: $8000 * .2 = $1600. Finally, subtract the discount from the total cost to find the final amount Jackson pays: $8000 - $1600 = $6400. The answer is 6400.
Q: Oranges have 80 calories and cost $1.20 each. If Timmy has $10 and needs to make sure he gets 400 calories, how much money will he have left after he buys the oranges he needs?
A: He needs to buy 5 oranges because 400 / 80 = 5. These will cost $6 because 5 x 1.2 = 6. He will have $4 left because 10 - 6 = 4. The answer is 4.
Question: Tom needs to lower a rope down 6 stories. One story is 10 feet. The only rope being sold is 20 feet long but you lose 25% when lashing them together. How many pieces of rope will he need to buy?
Answer: He needs 10 * 6 = 60 feet. He loses 20 * .25 = 5 feet each time. So he gets 20 - 5 = 15 feet from each piece. That means he needs 60 / 15 = 4 pieces of rope. The answer is 4.
Q: Leah bought 3 boxes of birdseed. When she went to put them away, she discovered that she already had 5 boxes in the pantry. Her parrot eats 100 grams of seeds each week and her cockatiel eats 50 grams of seeds in a week. If each box of birdseed contains 225 grams, for how many weeks can she feed her birds without going back to the store?
A:
In a week, her birds eat a total of 100 grams + 50 grams = 150 grams of seed each week. Leah has a total of 3 + 5 = 8 boxes of birdseed. The boxes of birdseed contain a total of 8 * 225 grams = 1800 grams. This is enough birdseed to feed her pets for 1800 / 150 = 12 weeks. The answer is 12.
