Explanation

Wildlife viewing in 2019: 10% of 200,000 = 20,000. Wildlife viewing in 2022: 20% of 200,000 = 40,000. Percentage change = ((40,000 - 20,000) / 20,000) * 100 = 100 percent.

AI explanation

In 2019, the number of visitors participating in wildlife viewing was 10 percent of 200,000, which equals 20,000. In 2022, the number of visitors participating in wildlife viewing was 20 percent of 200,000, which equals 40,000. The percentage change formula is ((Final Value - Initial Value) / Initial Value) * 100, so ((40,000 - 20,000) / 20,000) * 100 equals a 100 percent increase.
