<PRE><B>Question 627483</B>
To estimate animal populations, biologists count the total number of animals in a small section of a habitat. The total population of animals is directly proportional to the size of the habitat (in acres) polled.
----
 
a. Write an equation using only one variable that could be used to solve for the constant of variation k.
a = kh
----------- 
b. A biologist counted 12 white tail deer in a 100-acre parcel of land in a nature preserve. Find the constant of variation k.
12 = k*100
k = 0.12
------------------------ 
c. If the entire nature preserve is 2,500 acres, then what is the total white tail deer population in the preserve? Describe how you arrived at your answer.
------
# of deer = 0.12*2500 = 300
