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?
\(\frac{(h_{f}-h_{o})}{h_{o}} *100\)
\(\frac{(43-36)}{36} *100\)
\(\frac{7}{36} *100\)
\(0.1944*100\)
19.44
19.44% increase
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
