Question

To track the reptile population around a lake, researchers marked 36 turtles. A few weeks later, they counted 400 turtles, of which 20 were marked. To the nearest whole number, what is the best estimate for the turtle population?

Answer 1

Answer: 720

Explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720
