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 growth of the finch population, we can divide the total increase in the population by the number of years over which the increase occurred.

Given:

• Total increase in finches = 75 finches
• Time period = 3 years

We can calculate the annual increase as follows:

$$\text{Annual Increase}=\frac{\text{Total Increase}}{\text{Number of Years}}=\frac{75\text{ finches}}{3\text{ years}}=25\text{ finches per year}$$

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