Frogs: The population of a species of frog declines by 24% every year. Suppose 100 frogs are released into a pond. Which exponential model represents this population?

p = 100(1 + 0.24)^n

Step-by-step explanation:

If this were exponential growth, we'd use the model p = 100(1 + 0.24)^n, where n is the number of years.  But here we have exponential decline, which requires subtracting 0.24 in the formula instead of adding it to 1:

p = 100(1 - 0.24)^n = 100(0.76)^n

Next time, please share the given answer choices.  Thanks.
