    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:

    \frac{\text{New Value - Original Value}}{\text{Original Value}} \times 100 \%

    Original value is the population in 1991 and the New value is the population in 1992.

    Using the values, we get:

    \frac{30-25}{25} \times 100 \%\\\\ = 20%

    Thus, the deer population increased by 20% from 1991 to 1992
