Q: Lulu has $65 in her piggy bank. She spent $5 on ice cream. She then spent half of the remainder of the money on a t-shirt. Afterwards, she went to the bank and deposited a fifth of her remaining money. How much cash was Lulu left with?
A: Lulu had 65 - 5 = 60 dollars left after eating ice cream. Lulu had 60 / 2 = 30 dollars left. Lulu deposited 30 / 5 = 6 dollars. Lulu was left with 30 - 6 = 24 in cash. The answer is 24.
Question: Every year in January, Natalia, the librarian, tidies up the books. She has 145 novels, 271 comics, 419 documentaries, and 209 albums to store. She wants to put these in crates that can hold 9 items. How many crates will Natalia use?
Answer: Let's first calculate the total number of items: 145 + 271 + 419 + 209 = 1044 items. Now let's put the items in the crates: 1044 / 9 = 116 crates. The answer is 116.
[Question]Daniel has 5 jars of juice containing 2 liters each. He wants to serve a full glass of juice to each person at a party. He knows that each glass can hold up to 250 milliliters of juice. How many full glasses can he give?
[Answer]The total liters of juice he has is 5 jars x 2 liters / jar = 10 liters of juice. Then he needs to convert this amount to milliliters: 10 liters x 1000 milliliters / liter = 10,000 milliliters. He can fill up to 10,000 ml / 250 ml / glass = 40 glasses. The answer is 40.
Q: Jack and Jill went up the hill to fetch water to fill a 600 gallon tank. Each bucket is five gallons. Jack is stronger, and is able to carry two buckets of water at a time, but Jill can only manage one. Also, Jack can complete three trips to the well and back in the time it takes Jill to make two trips. How many trips will Jill make before the tank is filled?
A: Jack is able to carry two 5 - gallon buckets of water per trip, or 2 * 5 = 10 gallons of water. Jill can only carry one bucket per trip, or 5 gallons. Jack completes 3 trips to the well and back for every 2 trips Jill completes, so in that time they have both together carried 3 Jack trips * 2 buckets per Jack trip * 5 gallons per bucket + 2 Jill trips * 1 bucket per Jill trip * 5 gallons per bucket = 30 gallons + 10 gallons = 40 gallons of water. If you consider these as a single "group" of trips, it will take 600 gallons / 40 gallons per "group" of trips = 15 groups of trips. As each of these "groups" of trips consists of two Jill trips, Jill will make 15 * 2 = 30 trips to the well and back before the tank is filled. The answer is 30.
Question: Laura is hosting a carwash. She will charge $5 for a car, $6 for a truck, and $7 for an SUV. They raised $100 in total. If they washed 5 SUVs and 5 trucks, how many cars did they wash?
Answer:
They earned $30 from trucks because 5 x 6 = 30. They earned $35 from SUVs because 5 x 7 = 35. They earned $35 from cars because 100 - 35 - 30 = 35. They washed 7 cars because 35 / 5 = 7. The answer is 7.
