Final answer:

The number of aardvarks last year was calculated using the exponential growth formula, which resulted in approximately 700 aardvarks. The fraction of 0.6 is not considered since we cannot have a fraction of an aardvark. the correct answer is A

Step-by-step explanation:

To determine the number of aardvarks there were last year, given the current population and growth rate, we can use the formula for exponential growth. The formula is:

P0 = P / (1 + r)^t

where:

  • P0 is the initial population (number of aardvarks last year),
  • P is the present population (714 aardvarks),
  • r is the growth rate (0.02 for 2%), and
  • t is the time in years (1 year).

Substituting the given values into the formula, we get:

P0 = 714 / (1 + 0.02)^1

P0 = 714 / 1.02

P0 = 700

Therefore, there were approximately 700 aardvarks last year. the correct answer is A
