Question

Game wardens use experiments to help determine the number of deer in the state of North Carolina. Suppose 120 deer are caught, tagged, and released into the wild. A month later, 800 deer are caught with 16 found to have tags. Using this information, estimate the number of deer in North Carolina.
A. 50
B. 500
C. 600
D. 6,000

Answer 1

Given;
120 deer tagged
800 deer caught
16 out of 800 deer caught have tags

This is a proportion problem

a/b = c/d where ac = bd

16/800 = 120/d
16d = 800*120
16d = 96,000
d = 96,000 / 16
d = 6,000

The estimate number of deer in North Carolina is D. 6,000
