My question is: There are 2000 pinecones on the ground. 20% are eaten by reindeer. Twice as many are eaten by squirrels as reindeer. 25% of the remainder are collected to make fires. How many pinecones are left? Your thoughts:
First find the number of pinecones eaten by reindeer: 20% * 2000 pinecones = 400 pine cones. Then find the total number of pinecones eaten by squirrels: 400 pine cones * 2 = 800 pine cones. Then subtract those two amounts to find the number of pinecones left: 2000 pinecones - 400 pine cones - 800 pine cones = 800 pinecones. Divide that number by 4 to find the number that are collected for fires: 800 pinecones / 4 = 200 pine cones. Then subtract that number from the 800 pinecones to find the total left on the ground: 800 pine cones - 200 pinecones = 600 pine cones. The final answer: 600.
