Question

A tree grew from 4ft to 12ft in 3 years. What is the percent of increase?

Answer 1

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.

$\frac{percent Increase }{100} =\frac{Amount of change }{Original amount }$

Or ,$\frac{Percent Increase }{100} =\frac{8}{4}$

Cross multiplying we have:

4 ( percent Increase )= 800

Dividing by 4 we have Percent change = 200

Percent Increase = 200%.

Answer 2

It grew about i dont know if im right but ill say  27%
