Answer:

Percent increase is a percent change that describes an increase in quantity

To determine percent increase we first find the amount of change

It is given:A tree grew from 4ft to 12ft in 3 years .

Amount of change =12-4=8 ft.

We use proportion to find percent increase.

Or ,

Cross multiplying we have:

4 ( percent Increase )= 800

Dividing by 4 we have Percent change = 200

Percent Increase = 200%.
