[Question]Remi wants to drink more water. He has a refillable water bottle that holds 20 ounces of water. That week Remi refills the bottle 3 times a day and drinks the whole bottle each time except for twice when he accidentally spills 5 ounces the first time and 8 ounces the second time. In 7 days how many ounces of water does Remi drink?
[Answer]Remi drinks the same amount of water every day for a week except for when he spills some of it. His water bottle holds 20 ounces which he drinks 3 times a day, 20 x 3 = 60 ounces a typical day. Over 7 days, without spilling anything, Remi drinks 60 ounces x 7 days = 420 ounces. Except Remi spills 8 + 5 ounces of water during the week = 13 ounces of water Remi spills. Total, Remi drinks 420 ounces - 13 ounces of spilled water = 407 ounces Remi drank during the week. The answer is 407.
Q: Aaron wants to purchase a guitar under a payment plan of $100.00 per month for 12 months. His father has agreed to lend him the entire amount for the guitar, plus a one-time 10% interest fee for the entire loan. With interest, how much money will Aaron owe his dad?
A: The guitar costs $100 every month for 12 months so it costs 100 * 12 = $1200. His dad is charging him 10% interest on the $1200 so interest comes to .10 * 1200 = $120.00. All total, Aaron will owe his father the price of the guitar, $1200 and the interest, $120 so 1200 + 120 = $1,320.00. The answer is 1320.
Question: Toby has 63 photos on his camera roll. He deletes seven bad shots, takes fifteen pictures of his cat, and then does a photo shoot with his friends. After editing the photos with his friends, he decides to delete three of them. His camera roll has 84 photos in the end. How many photos did Toby take in the photo shoot?
Answer: Let P be the number of photos in the photo shoot. After Toby deleted 7 shots, he had 63 - 7 = 56 photos. After taking 15 cat pictures, he had 56 + 15 = 71 photos. After the photo shoot, he had 71 + P photos. After deleting 3 photos, he had 71 + P - 3 = 68 + P photos. He had 68 + P = 84 photos in the end. Thus, Toby took P = 84 - 68 = 16 photos in the photo shoot. The answer is 16.
[Question]Mary bought six apples from the store. From the apples she bought, for each that Mary ate, she planted two trees from the remaining ones. How many apples did Mary eat?
[Answer]She planted eight trees. This means she used half of that amount of apples, which is 8 trees / 2 trees / apple = 4 apples. That means that she planted four of the six apples she bought, leaving only 6 apples - 4 apples = 2 apples to be eaten. The answer is 2.
[Question]Kevin has been for a run and wants to calculate how far he traveled. He ran at 10 miles per hour for half an hour, 20 miles per hour for half an hour, then ran at 8 miles per hour for 15 minutes. How many miles has Kevin run?
[Answer]
At his first speed, Kevin ran 10 miles per hour * 0.5 hours = 5 miles. At his second speed, he ran 20 miles per hour * 0.5 hours = 10 miles. 15 minutes is a quarter of an hour so at his third speed, he ran 8 miles per hour * 0.25 hours = 2 miles. Therefore, Kevin ran a total of 5 miles + 10 miles + 2 miles = 17 miles. The answer is 17.
