Question

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

Answer 1

Answer: 36 - 100%

43 - x  %

Step-by-step explanation 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 - 100

x = 119+ 16/36 -100

x = 19 +4/9
