You catch ,tag ,and release 35 fish back into a pond . then, you catch 70 more fish , 12 of which have tags on them . what is the best estimate of the number of fish in the proof?

x - 93

Explanation:

Thinking process:

This is a  subtraction problem.

let the total number of fish caught be x

The number of fish tagged = 35 + (70-12)

                                             = 35 + 58

                                             = 93

However, the number of fish is not known. Therefore, the number of fish in the pool cab be given as x - 93.
