Lizzy: The total number of lions in a park is twice the number of leopards in the same park. The number of elephants is half the combined number of lions and leopards. Calculate the total population of the three animals in the park if the number of lions is 200..
Me: Hmmm, let me think. I think this is the detailed solution:
If there are 200 lions in the park, which is twice the number of leopards in the park, there are 200 / 2 = 100 leopards in the park. The total population of lions and leopards in the park is 200 lions + 100 leopards = 300. The number of elephants in the park is 1 / 2 the total population of lions and leopards; thus, there are 300 / 2 = 150 elephants in the park. There are a total of 150 + 300 = 450 animals in the park. Final answer: 450.
