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?

1 answer

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.
