Question

To determine the number of deer in a game preserve, a conservationist catches 443, tags them and then lets them loose. Later, 528 deer are caught and 176 are tagged. How many deer are in the preserve?

What formula do I use to find the answer to this?

Thank you for helping if you can.

Answer 1

176 is 1/3 of 528.

We can assume, then, that the total number of deer is 3 times 443 = 1329.
