Answer:
20%
Step-by-step explanation:
Population of white-tailed deer in 1991 = 25 deer per square mile
Population of white-tailed deer in 1992 = 30 deer per square mile
We have to find the percentage increase in the deer population. The formula for percentage change is:
[tex]\frac{\text{New Value - Original Value}}{\text{Original Value}} \times 100 \%[/tex]
Original value is the population in 1991 and the New value is the population in 1992.
Using the values, we get:
[tex]\frac{30-25}{25} \times 100 \%\\\\ = 20%[/tex]
Thus, the deer population increased by 20% from 1991 to 1992
