Question: Wayne wants to serve shrimp cocktail as an appetizer. He plans on 5 shrimp per guest and will have 40 guests. If the shrimp costs $17.00 per pound and each pound has 20 shrimp, how much will he spend on the appetizer?
Answer: Step-by-step reasoning process: He wants to serve 5 shrimp per guest and will have 40 guests so he needs 5 * 40 = 200 shrimp. Each pound of shrimp has 20 shrimp and he needs 200 shrimp so he needs 200 / 20 = 10 pounds of shrimp. The shrimp is $17.00 per pound and he needs 10 pounds so he will spend 17 * 10 = $170.00 on shrimp.
So the answer is 170.

Question: Fern is checking IDs to get into an R-rated movie. She denied 20% of the 120 kids from Riverside High, 70% of the 90 kids from West Side High, and half the 50 kids from Mountaintop High. How many kids got into the movie?
Answer: Step-by-step reasoning process: First find how many kids from Riverside High are rejected: 20% * 120 kids = 24 kids. Then find how many kids from West Side High are rejected: 70% * 90 kids = 63 kids. Then find how many kids from Mountaintop High are rejected: 50 kids / 2 = 25 kids. Then add the number of kids from each school to find the total number of kids: 120 kids + 90 kids + 50 kids = 260 kids. Then subtract all the kids who were rejected from the total number of kids to find the number who got in: 260 kids - 24 kids - 63 kids - 25 kids = 148 kids.
So the answer is 148.

Question: Today, at the school science lesson, Jake learned that there are 8 more solar systems for every planet in the galaxy. If there are 20 planets in the galaxy, how many solar systems and planets are there altogether?
Answer: Step-by-step reasoning process: If there are 8 more solar systems for every planet in the galaxy, there are 8 + 1 = 9 solar systems for every planet. Since the number of planets is 20, there are 20 * 9 = 180 solar systems in the galaxy. Altogether, there are 180 + 20 = 200 solar systems and planets in the galaxy.
So the answer is 200.

Question: Hershel has 10 betta fish and 15 goldfish in a bowl. His friend Bexley brings him 2/5 times as many betta fish and 1/3 times as many goldfish. If Hershel gifts his sister 1/2 of the fish, calculate the total number of fish he has remaining in the bowl.
Answer:
Step-by-step reasoning process: Bexley gives Hershel 2 / 5 * 10 = 4 betta fish. The total number of betta fish in the bowl is now 4 + 10 = 14. He also gives Hershel 1 / 3 * 15 = 5 goldfish. The total number of goldfish in the bowl is now 15 + 5 = 20. Counting the betta fish and goldfish, Hershel now has a total of 14 + 20 = 34 fish. When he gives his sister half of the fish, the remaining half is 34 / 2 = 17 fish.
So the answer is 17.
