[Question]Jenna sets a goal of reading 600 pages a month for the month of September (which has 30 days). She knows that she'll be really busy at work the four weekdays starting on the 13th, so she won't have time to read. She can also read 100 pages on the 23rd, when she'll have a long boring flight. If she reads the same number of pages every other day, how many pages a day does she need to read?
[Answer]First, subtract the number of days Jenna can't read from the number of days in September: 30 days - 4 days = 26 days. Then subtract the one day when Jenna will read 100 pages: 26 days - 1 day = 25 days. Now subtract the 100 pages Jenna will read on her flight from her overall goal: 600 pages - 100 pages = 500 pages. Finally, divide that number of pages by the number of days Jenna will read the standard amount: 500 pages / 25 days = 20 pages per day. The answer is 20.

[Question]Tony made a sandwich with two slices of bread for lunch every day this week. On Saturday, he was extra hungry from doing yard work and made two sandwiches. How many slices of bread are left from the 22-slice loaf Tony started with?
[Answer]There are 7 days in a week, so Tony made 1 * 7 = 7 sandwiches. On Saturday, he made 1 extra sandwich, so he made 7 + 1 = 8 sandwiches this week. A sandwich has 2 slices of bread, so he used 8 * 2 = 16 slices. Thus, Tony has 22 - 16 = 6 slices of bread left. The answer is 6.

[Question]Louise is in a toy store. She already has 28 toys worth $10 each in her cart. On her way to the till she adds 20 teddy bears to the cart. If the $580 in Louise’s wallet is exactly enough to pay for all the toys, how much does each teddy bear cost?
[Answer]Initially, Louise's cart has toys worth 10 * 28 = 280 dollars. If Louise pays for the toys originally in her cart, her wallet will remain with 580 - 280 = 300 dollars. Dividing the remaining amount by the number of teddy bears gives 300 / 20 = 15 dollars. The answer is 15.

[Question]There are three goldfish and ten platyfish in a fish tank. Each goldfish plays with ten red balls, while each platyfish plays with five white balls. What is the total number of balls in the fish tank?
[Answer]
If there are 3 goldfish, and each is playing with ten red balls, then the number of red balls in the tank is 3 * 10 = 30. There are also ten platyfish playing with 5 white balls, there are 10 * 5 = 50 white balls. The total number of red and white balls in the fish tank is 50 + 30 = 80. The answer is 80.
