[Question]There's a Bobbit worm hiding in the bottom of James' aquarium. Every day it eats 2 fish. After two weeks, James adds 8 more fish to the aquarium. A week later, he discovers the Bobbit worm. If the aquarium had 60 fish to start with, how many does it have when James discovers the Bobbit worm?
[Answer]First find the total number of weeks the Bobbit worm preys on the fish: 2 weeks + 1 week = 3 weeks. Then multiply that number by the number of days per week: 3 weeks * 7 days / week = 21 days. Then multiply that number by the number of fish the worm eats per day to find how many fish it eats total: 21 days * 2 fish / day = 42 fish. Then add the number of fish James adds to the starting number of fish to find the ending number of fish: 60 fish + 8 fish = 68 fish. Then subtract the number of eaten fish to find the number of surviving fish: 68 fish - 42 fish = 26 fish. The answer is 26.
Q: Wally gives 3/4 of his 400 tickets to his two friends Jensen and Finley, who share the tickets in a ratio of 4:11. How many tickets does Finley get?
A: Wally gives his friends 3 / 4 * 400 = 300 tickets to share. The total ratio that represents the tickets that Jensen and Finley share is 4 + 11 = 15. From the total ratio, the fraction that represents the share that Finley got is 11 / 15, and since he shared with Jensen 300 tickets, he got 11 / 15 * 300 = 220 tickets. The answer is 220.
Question: Marnie opens a bag of chips and eats 5 of them to see if she likes them. She does, so she eats 5 more. The bag has 100 chips in it and starting on the second day she has them, Marnie eats 10 each day. How many days does it take for Marnie to eat the whole bag of chips?
Answer:
Marnie has already eaten 5 of the chips + 5 more = 10 chips Marnie ate. The bag has 100 chips in it and Marnie has only eaten 10, 100 - 10 = 90 chips left. If Marnie eats 10 chips a day starting from the second day she has them, it will take her 90 chips in the bag / 10 chips Marine eats a day = 9 days to eat the whole bag. However, Marnie also ate chips on the first day she bought them, so 9 + 1 = 10 days to eat the whole bag. The answer is 10.
