Question

Samantha is L50 rn tall on her eleventh birthday and 1.65 rn tall on her twelfth birthday. By what factor has her heightincreased? By what percentage?

Answer 1

Factor of 1.1

10%

Step-by-step explanation:

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

`\begin{array}{cc}Age&Height\\11&1.50\\12&1.65\end{array}`

The factor F by which her height changed is:

`F=(1.65)/(1.50)\\ F=1.1`

The percentage increase in her height is:

`P = (1.65-1.5)/(1.5)=0.1=10\%`
