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?
How many weeks does the Bobbit worm prey on the fish? ** First find the total number of weeks the Bobbit worm preys on the fish: 2 weeks + 1 week = <<2+1=3>>3 weeks
How many days does the Bobbit worm prey on the fish? ** Then multiply that number by the number of days per week: 3 weeks * 7 days/week = 21 days
How many fish does the Bobbit worm eat? ** 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 = <<21*2=42>>42 fish
How many fish does James add? ** 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 = <<60+8=68>>68 fish
How many fish does James have left? ** Then subtract the number of eaten fish to find the number of surviving fish: 68 fish - 42 fish = <<68-42=26>>26 fish
