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
