Question

A scientist is observing the grizzly bear population in two state parks. The parks each

have 150 bears when he begins observing them. The population in Park A increases
by 20% each year. The population in Park B decreases by 20% each year.
In each equation, y represents the bear population with respect to a number of years, X.
Drag each equation to show whether it can be used to represent the bear population in
Park A, Park B, or neither of these.

Answer 1

Park A-y=150(1+0.20)^x
Y=150(6/5)^x
Park B-150(1-0.2)^x
150(4/5)^x
The last two go in neither
