Answer:

N = 187.55

Explanation:

Here you just need to replace the terms and clear the equation.

You already know that,

First capture: 25 prairie dogs.
First marked animals: 25 (the whole first capture)

You let these animals leave and then you made another capture.

Second capture: 135 prairie dogs
Already Marked animals: 18 (these 18 dogs were caught in the first capture and marked before releasing them)

To know the size of the prairie dogs population you just need to use the following equation and clear N, which is the value that you are looking for.

Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch

Number of individual marked in first catch = 25 dogs
Total population size, N = this is what we want to know
Number of individual marked in 2nd catch = 18 dogs
Total number of 2nd catch = 135 dogs

So now, we need to replace terms

25 / N = 18 / 135

25 / N = 0.1333

N = 25 / 0.1333

N = 187.55
