Answer:
400
Explanation:
Scientists tagged 80 hitch. When they capture 100 hitch, 20 are tagged. In order to estimate the population of hitch, we can assume that this proportion is consistent.
This means for every 20 tagged hitch, there are 80 untagged. We know there are 80 tagged total, so we need to multiply 20 by 4 to get it to 80. To keep the proportion equal we also need to multiply the untagged hitch.
*
=
Still following the proportion, we have 80 tagged hitch and 320 untagged hitch. 80 + 320 = 400 hitch total.
