Answer:

Factor of 1.1

10%

Explanation:

The following table presents Samantha's change in height with age:

[tex]\begin{array}{cc}Age&Height\\11&1.50\\12&1.65\end{array}[/tex]

The factor F by which her height changed is:

[tex]F=\frac{1.65}{1.50}\\ F=1.1[/tex]

The percentage increase in her height is:

[tex]P = \frac{1.65-1.5}{1.5}=0.1=10\%[/tex]
