Answer: 720
Step-by-step 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
