b: Use a proportion to estimate the turtle population for 2010
HELP MEE!!!!! I am stuck am 2010

Answer 1

We know that there are 40 turtles tagged.

In 2009, 16/50 = 32% of the population was tagged, making the population 40/.32 = 125 (P/40 = 50/16)

In 2010, 8/30 = 26.7% of the population was tagged. So, the population is about 150 (P/40 = 30/8)
