Answer:
In this problem we only want to know the exponential growth of the population at a certain time, that is to say, three years, which means that its growth must be greater.
Explanation:
For this we determined the initial growth of the population at one year which is 250.
So making a rule of three:
1 year = 250
3 years = x
So, we have:
250 x 3 = 750; that is, the exponential growth in the third year is equivalent to 750.
