Answer: This population, the population is 45 fish.

Step-by-step explanation: This problem can be solved by a rule of three.

Last year there were 60 fish in the lake. That was 100, that is, decimal 1.

This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So

60 fish - 1

x fish - 0.75

This population, the population is 45 fish.

2. So you need to find x

3. So basically if you set up the equation 61x - 2 = 13x - 1 + 95

4. Then you can solve for x

5. X = 2
