The department of natural resources determined that the population of white-tailed deer in one of indiana's state parks was 25 deer per square mile in 1991. by 1992, the population had increased to 30 deer per square mile. by what percentage does the deer population increase in this time frame?

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:

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

Using the values, we get:

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

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

if x = 2 you have to find x to finish the problem
