Q: Andrew holds a bake sale to fundraise for charity. The bake sale earns a total of $400. Andrew keeps $100 to cover the cost of ingredients. He donates half of the remaining total to the local homeless shelter, and the other half to the local food bank. Andrew also decides to donate $10 from his own piggy bank to the local homeless shelter. How much money in total does Andrew donate to the homeless shelter?
A: After paying off the cost of ingredients, Andrew has $400 - $100 = $300. Since half of the money goes to the homeless shelter, the shelter receives $300 / 2 = $150. After contributing some of his own money, Andrew donates $150 + $10 = $160 to the shelter. The answer is 160.
Question: Alyssa took 100 photos on vacation. She wants to put them in a photo album with 30 pages. She can place 3 photos each on the first 10 pages. Then she can place 4 photos each on the next 10 pages. If she wants to put an equal number of photos on each of the remaining pages of the album, how many photos can she place on each page?
Answer: There are 3 x 10 = 30 photos in total that can be placed in the first 10 pages. There are 4 x 10 = 40 photos in total that can be placed in the next 10 pages. A total of 10 + 10 = 20 pages of the album have been used. A total of 30 + 40 = 70 photos can be placed on those 20 pages. So there are still 100 - 70 = 30 photos left to be placed on the album. And there are 30 - 20 = 10 pages left in the album. Therefore, 30 / 10 = 3 photos can be placed on each of the pages. The answer is 3.
[Question]A jug needs 40 cups of water to be full. A custodian at Truman Elementary School has to fill water jugs for 200 students, who drink 10 cups of water in a day. How many water jugs will the custodian fill with cups of water to provide the students with all the water they need in a day?
[Answer]Since each student needs 10 cups of water per day and there are 200 students, the custodian has to provide 200 * 10 = 2000 cups of water. A jug of water needs 40 cups to be full, so 2000 cups of water will fill 2000 / 40 = 50 jugs. The answer is 50.
Q: Max likes to collect model trains. He asks for one for every birthday of his, and asks for two each Christmas. Max always gets the gifts he asks for, and asks for these same gifts every year for 5 years. At the end of the 5 years, his parents give him double the number of trains he already has. How many trains does Max have now?
A: Max gets 1 + 2 = 3 trains per year. He repeats this for 5 years, meaning he gets 5 * 3 = 15 trains. When this number is doubled by his parents, it becomes 15 * 2 = 30 trains. Since he already had 15 model trains, his total becomes 15 + 30 = 45 trains. The answer is 45.
Question: Aubriella is pouring water into a 50-gallon fish tank at the rate of 1 gallon every 20 seconds. How many more gallons will she have to pour into the tank to fill the tank if she poured water into the fish tank for 6 minutes?
Answer: When she poured water into the gallon for 6 minutes, the total time in seconds she took is 6 minutes * 60 seconds / minute = 360 seconds. If in 20 seconds she poured 1 gallon of water into the tank, in 360 seconds, she poured 360 seconds / 20 seconds / gallon = 18 gallons of water into the tank. Aubriella will have to pour 50 gallons - 18 gallons = 32 more gallons into the tank to fill the tank. The answer is 32.
Q: If 1 ounce of Dawn liquid soap can make 200,000 bubbles, and Dr. Bronner's liquid soap can make twice as many bubbles per ounce as Dawn liquid soap, then how many bubbles can be made from one half ounce of an equal mixture of Dawn and Dr. Bronner's liquid soaps?
A:
One half of a 1 / 2 - ounce liquid is (1 / 2) * (1 / 2) = 1 / 4 ounces. 1 / 4 ounce of Dawn liquid soap can make (1 / 4) * 200,000 = 50,000 bubbles. 1 / 4 ounce of Dr. Bronner's liquid soap can make 2 * (1 / 4) * 200,000 = 100,000 bubbles. Therefore, a half ounce of an equal mixture of Dawn and Dr. Bronner's liquid soaps can make 50,000 + 100,000 = 150,000 bubbles. The answer is 150000.
