Question

A tree farm initially has

9000 trees. Each year, 10% of the trees are harvested
and 800 seedlings are planted.
a. Write a recursive rule for the number of trees on
the tree farm at the beginning of the nth year.
b. What happens to the number of trees after an
extended period of time?

Answer 1

y(0)=5000

y(1)=y(0)-.1(y(0)+450

y(1)=.9y(0)+450

y(n)=.9y(n-1)+450
