(6) The number of fish in a lake is estimated to be 2,000 After a conservation project, the number of fish in the lake is estimated to have increased by \( 65 \% \). About how many fish are there in the lake now?

To find the new number of fish in the lake after a 65% increase, we can calculate it as follows: First, calculate 65% of 2,000, which is \( 2,000 \times 0.65 = 1,300 \). Then, we add that to the initial number of fish: \( 2,000 + 1,300 = 3,300 \). So, there are approximately 3,300 fish in the lake now! Keep in mind that percentage increases can sometimes lead to high figures, especially with large populations or quantities. It's a useful way to quickly assess growth without needing detailed records, but it's always wise to verify those numbers through actual observation whenever possible!
