The percent of decrease in the number of endangered species can be calculated using the formula:
Percent Decrease = ((Initial Value - Final Value) / Initial Value) x 100%
In this case, the initial value is 75 and the final value is 30. Plugging these values into the formula:
Percent Decrease = ((75 - 30) / 75) x 100%
Percent Decrease = (45 / 75) x 100%
Percent Decrease = 0.6 x 100%
Percent Decrease = 60%
Therefore, the correct answer is 60%.
