Question: Donna is catering for a party. She makes 20 sandwiches and then cuts them in half, before cutting them in half again. She then gives everyone 8 portions. How many people can she feed?
Answer: First, we need to determine the overall number of portions. To do this, we begin by performing 20 * 2 = 40 portions after the first halving. Next, we take this portion number and double it again, performing 40 * 2 = 80 portions after the second halving. Lastly, we divide this portion number by the number of portions each person will be served, performing 80 / 8 = 10 people served. The answer is 10.

Q: Each bird eats 12 beetles per day, each snake eats 3 birds per day, and each jaguar eats 5 snakes per day. If there are 6 jaguars in a forest, how many beetles are eaten each day?
A: First find the total number of snakes eaten: 5 snakes / jaguar * 6 jaguars = 30 snakes. Then find the total number of birds eaten per day: 30 snakes * 3 birds / snake = 90 snakes. Then multiply the number of snakes by the number of beetles per snake to find the total number of beetles eaten per day: 90 snakes * 12 beetles / snake = 1080 beetles. The answer is 1080.

[Question]In the beginning, Justine had 10 more rubber bands than Bailey but 2 fewer bands than Ylona. Bailey decided to give two bands each to Justine and Ylona so that he is left with only 8 rubber bands. How many rubber bands did Ylona have in the beginning?
[Answer]Bailey gave 2 + 2 = 4 bands. So Bailey had 8 + 4 = 12 bands in the beginning. Justine had 12 + 10 = 22 bands in the beginning. Thus, Ylona had 22 + 2 = 24 bands in the beginning. The answer is 24.
[Question]Lily has 5 lottery tickets to sell. She sells the first ticket for $1. She then sells each successive ticket for a dollar more than the previous ticket. She plans to keep a $4 profit and give the remaining money as the prize. How much money will the winner of the lottery receive?
[Answer]
The second ticket sold will cost $1 + $1 = $2. The third ticket sold will cost $2 + $1 = $3. The fourth ticket sold will cost $3 + $1 = $4. The fifth ticket sold will cost $4 + $1 = $5. The total money collected is $1 + $2 + $3 + $4 + $5 = $15. After taking profit, the total prize money will be $15 - $4 = $11. The answer is 11.
