Question

You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of increase in the tree's height?

Answer 1

36 - 100%43 - x %
we multiply by cross -> 36 * x = 100 / 43
we should remove '100%' from new value, because we find only increase.. no new value in percent.
x + 100 = (43 * 100)/36
x = 4300/36 - 100x = 119+ 16/36 -100x = 19 +4/9



the answer is

19.44% increase

Answer 2

HOW TO FIND THE GROWTH PERCENTAGE:


Percent Problem:
You need to calculate percent increase from 36 to 43.

First Step: Find the difference between two numbers, in this case, it's 10 - 2 = 8.

Second Step: Take the difference, 7, and divide by the original number: 7/36 = 0.194444.

Last, convert the decimal to a percent.

FINAL ANSWER: 19.44%
