The finch population in an area increased by 75 finches in 3 years, the finch population increased at the same rate each year, how many finches did the population grow by each year

Answer 1

To find the annual increase in the finch population, you can divide the total increase over the 3 years by the number of years.

The total increase in the finch population is 75 finches, and this increase occurred over 3 years.

So, the annual increase is calculated as follows:

\[ \text{Annual increase} = \frac{\text{Total increase}}{\text{Number of years}} = \frac{75 \text{ finches}}{3 \text{ years}} = 25 \text{ finches/year} \]

Therefore, the finch population grew by 25 finches each year.
