To answer this question, we have to take into account the following:
The amount of increase can be determined as follows:
[tex]728-560=168[/tex]That is, we subtracted 560 from the increased amount. Therefore, we have that:
[tex]\begin{gathered} P_{}=\frac{(728-560)}{560}\cdot100\% \\ P=\frac{168}{560}\cdot100\% \\ P=(0.3)\cdot100\% \\ P=30\% \end{gathered}[/tex]In summary, the percent of the increase is 30%.
