A wooded area in a state park has a mixture of different types of trees. There are 800 pine trees and 50 oak trees. The number of pine trees is decreasing at a rate of 5% per year. The number of oak trees is increasing at a rate of 15% per year. If these trends continue:
A. Write two functions to model this situation and graph those two functions on the same coordinate grid. Two functions for this model would be:
y = 800(.95)^x
y = 50(1.15)^x

B. During what year in the future will the park have approximately the same number of pine and maple trees?
~During the 14th year they will have approximately the same number od pine a and maple trees.

C. How many of each type of tree will there be at that time? There will be about 380 pine trees and 379.39 oak trees. This is what I think, hope it helps :)
