Ginny is studying a population of frogs. she determines that the population is decreasing at an average rate of 3% per year. when she began her study, the frog population was estimated at 1,200. choose the function that represents the frog population after x years. a. f(x) = 1,200(1.03)xb. f(x) = 1,200(0.03)xc. f(x) = 1,200(0.97)xd. f(x) = 1,200(0.97)x

Step-by-step explanation:

For population decrease, if the rate of decrease is a% per year, the initial population is P, after time x, the equation to use would be:

From the info given, we can say that P = 1200, a = 3, and after x years, so:

Since answer choice C and D are same (typing mistake), which one has x to the power, i don't know. But the answer is  

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
