Q: Carla needs to drive her car to do a bunch of errands. She needs to drive 8 miles to the grocery store, 6 miles to pick up her kids from school, 12 miles to drop her kids off at soccer practice, and twice the distance from the school to soccer practice to get everyone home again. If Carla's car gets 25 miles per gallon, and gas costs $2.50, how much will Carla have to spend on gas for her trip?
A: First find the distance between soccer practice and home by multiplying the distance between soccer practice and school by 2: 12 miles * 2 = 24 miles. Then find the total distance Carla drives by adding the length of each trip: 24 miles + 12 miles + 6 miles + 8 miles = 50 miles. Then find how many gallons of gas she needs by dividing the distance of the trip by her car's gas mileage: 50 miles / 25 mpg = 2 gallons. Then multiple the gallons of gas by the price per gallon to find the total cost: 2 gallons * $2.50 = $5. The answer is 5.

Q: Natalie's sister had 8 small diaries in her locker. Last summer she bought double the number of diaries she had and then lost 1/4 of what she had. How many diaries does Natalie's sister have now?
A: Natalie's sister bought 2 * 8 = 16 diaries. So she then had 16 + 8 = 24 diaries. Afterwards, she loses 1 / 4 * 24 = 6 diaries. So, Natalie's sister now has 24 - 6 = 18 diaries. The answer is 18.

Q: Janice opened an art book that she had found in the library and found 5 drawings on the first page. After opening the first ten pages, she realized that the number of drawings on each page increased by five after every page. How many drawings were in the first five pages?
A:
If the first page had 5 drawings, and the number of drawings on each page increased by five, the second page had 5 + 5 = 10. The total number of drawings in the first 2 pages is 5 + 10 = 15. On the third page, the number of drawings increased to 10 + 5 = 15. The first three pages have a total of 15 + 15 = 30 drawings. The fourth page had 15 + 5 = 20 drawings. There are 30 + 20 = 50 drawings on the first four pages. The fifth page also had an extra 5 more drawings than the fourth page, totaling 20 + 5 = 25. For the first five pages, Janice saw 25 + 50 = 75 pages. The answer is 75.
