You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Write an expression which describes the percent of increase in the trees height?

Answers

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
((h_(f)-h_(o)))/(h_(o)) *100

((43-36))/(36) *100

(7)/(36) *100

0.1944*100

19.44

19.44% increase
