Q: Henry, John and Leo collected some seashells from the beach. Henry collected 11, Paul 24. If they initially collected 59 seashells in total and Leo gave a quarter of his collection to a younger kid they met, how many do they have in total now?
A: Henry and Paul collected a total of 11 + 24 = 35 seashells. To make a total of 59, Leo must have collected 59 - 35 = 24 seashells. He gave out a quarter of 24 seashells which is 24 * (1 / 4) = 6 seashells. They are now left with 59 - 6 = 53 seashells. The answer is 53.
Question: If Billy and Jenny each order a $20 steak along with a $5 drink, how much will Billy have to pay in tips if he wants to cover 80% of a 20% tip for the two of them?
Answer: First, we figure out the price per meal by adding the steak and the drink together, finding a cost of 20 + 5 = 25 per meal. Then we multiply this by 2, as there are two people eating, meaning a total cost of 25 * 2 = 50 for both meals. Then we find the total tip amount for a 20% tip, by multiplying 50 * .2 = 10. Then we find out what 80% of this tip amount is by multiplying the desired tip of 10 by .8, finding 10 * .8 = 8 dollars that Billy should contribute. The answer is 8.

Question: Brennan was researching his school project and had to download files from the internet to his computer to use for reference. After downloading 800 files, he deleted 70% of them because they were not helpful. He downloaded 400 more files but again realized that 3/5 of them were irrelevant. How many valuable files was he left with after deleting the unrelated files he downloaded in the second round?
Answer: The number of non - valuable files Brennan downloaded in the first round is 70 / 100 * 800 = 560 files. The number of valuable files Brennan downloaded in the first round is 800 - 560 = 240. When he downloaded 400 new files, there were 3 / 5 * 400 = 240 non - useful files, which he deleted again. The total number of valuable files he downloaded in the second round is 400 - 240 = 160. To write his research, Brennan had 160 + 240 = 400 useful files to reference to write his research. The answer is 400.
