Math
I believe it would be 42 I got that by multiplying her current height by the percentage that she grew. (36 in)(1.17%) The 1 being her current height and the .17 being what she grew = 1.17

math
108/87 = 1.2414 = 124.14% Then you subtract 100% of what you got because that was your original number 124.14% - 100% = 24.14% Its 24.14% increase

math
Another way you could do it is do 95/80 = 1.1875 x 100 = 118.75 Then subtract 100% from that 118.75% - 100% = 18.75% whoch rounds up to 18.8%
