Snowcat [4.5K]

Answer/Explanation:

Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:

<u>Year                       Calculation         Est. Population</u>

1st yr (current yr)                                   11,500

2nd yr                     11,500*105%          12,075

3rd yr                      12,075*105%         12,679

4th yr                      12,679*105%          13,313

5th yr                      13,313*105%           13,979

The above is how the table would like showing the estimated population for each year.
