Question

The fish population in a local stream is decreasing at a rate of 4% per year. The original population was 55,000 fish. What is the population of the fish pond after 9 years?

Answer 1

Answer: 38090 fish

Step-by-step explanation:

Use the equation 55,000(.96)^9. Start with the initial number in this case it is 55,000 then multiply by the percentage that remains (100% - 4% = 96%) and then put it to the ninth power because that is how many years the problem is asking for.
