We have to calculate the percentage change of the first quantity with reference to the second quantity.

The quantities are:

$\begin{gathered} X_1_{}=480 \\ X_2=560 \end{gathered}$

We then can calculate the percentage change as:

$\begin{gathered} p=(480-560)/(560)\cdot100\% \\ p=(-80)/(560)\cdot100\% \\ p=-0.1429\cdot100\% \\ p=-14.29\% \end{gathered}$

Answer: the percentage change of the first quantity with reference to the second quantity is -14.29%.
