Q: The first tank is 300 liters filled while the second tank is 450 liters filled. The second tank is only 45% filled. If the two tanks have the same capacity, how many more liters of water are needed to fill the two tanks?
A: Since 450 liters represents 45%, then each 1% is equal to 450 liters / 45 = 10 liters. Hence, the capacity of each tank is 10 liters x 100 = 1000 liters. So, the first tank needs 1000 - 300 = 700 liters of water more. While the second tank needs 1000 - 450 = 550 liters more. Therefore, 700 + 550 = 1250 liters of water are needed to fill the two tanks. The answer is 1250.
Question: The local school is holding a big fair to raise money for 5 classes that want to go on a trip. 150 people came to the party and paid a total of $368 for entrance tickets. There was a raffle which brought in $343. The sale of cakes and drinks brought $279. At the end of the fair, the principal of the school shared the money raised between the 5 classes. How much money did each class receive?
Answer: First, let's calculate the total amount of money collected, which is 368 + 343 + 279 = $990. Let us now share this sum between the 5 classes: 990 / 5 = $198. The answer is 198.
[Question]Tanesha needs to buy rope so cut into 10 pieces that are each six inches long. She sees a 6-foot length of rope that cost $5 and also sees 1-foot lengths of rope that cost $1.25 each. What is the least she has to spend to get the rope she needs?
[Answer]She needs 60 inches of rope because 10 x 6 equals 60. The six - foot length of rope is 72 inches long because 6 x 12 = 72. The six - foot length of rope would give her 12 pieces because 72 / 6 = 12. The six - foot length is long enough because 12 > 10. Each 1 - foot rope equals 12 inches. She would need 5 of the 1 - foot ropes because 60 / 12 = 5. If she bought one - foot ropes it would cost $6.25 because 5 x 1.25 = 6.25. The cheapest rope to buy is the 6 - foot rope because 5 < 6.25. The answer is 5.
Q: Wanda walks her daughter .5 miles to school in the morning and then walks .5 miles home. She repeats this when she meets her daughter after school in the afternoon. They walk to school 5 days a week. How many miles does Wanda walk after 4 weeks?
A: She walks .5 miles to school and back 4 times a day so that's .5 * 4 = 2 miles. She walks 2 miles a day for 5 days so that's 2 * 5 = 10 miles. Over 4 weeks of walking 10 miles per week she walks 4 * 10 = 40 miles. The answer is 40.
Question: Marcy uses 6 ounces of pet cleaner to clean up a dog stain, 4 ounces to clean up a cat stain, and 1 ounce to clean up a rabbit stain. How much cleaner does she need to clean up after 6 dogs, 3 cats and 1 rabbit?
Answer: First find the total amount of cleaner used for the dogs: 6 ounces / dog * 6 dogs = 36 ounces. Then find the total amount of cleaner used for the cats: 4 ounces / cat * 3 cats = 12 ounces. Then add the amount of cleaner used for each species to find the total amount used: 36 ounces + 12 ounces + 1 ounce = 49 ounces. The answer is 49.
