. Choose one of these towns. Use the second and third columns to write two
expressions showing the current estimated population of the town in terms of
x, y, or z

Answer 3

Let's choose the town Pleasantville.

The current estimated population of Pleasantville can be expressed using the second column as:

Population of Pleasantville = x + (-2% of x) = x - 0.02x = 0.98x

Therefore, the current estimated population of Pleasantville in terms of x is 0.98x.
