A breeding group of beavers is introduced into a protected area. After t years the number of beavers in the area is modeled by the function

N(t)= 54/0.35+0.68^t

1. How many beavers were initially introduced?
2. Estimate the number of beavers after 5 years.
3. Determine the change in the beaver population between t = 5 and t = 10.

(Note: All answers are whole numbers.)
