Answer 1

Answer 2

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.

`(percent Increase )/(100) =(Amount of change )/(Original amount )`

Or ,
`(Percent Increase )/(100) =(8)/(4)`

Cross multiplying we have:

4 ( percent Increase )= 800

Dividing by 4 we have Percent change = 200

Percent Increase = 200%.
