    Percent Change = [(final value - original value)/original value] x 100%

    Given:original value = $2.30

    final value = $2.45

    Percent Change = [(2.45 - 2.30)/2.30]•100%

     = (0.15/2.30) • 100%

     = 6.5%

    It is a percentage increase because it is greater than zero. Had it been less than zero, it would be a percentage decrease.

    Relative to the initial price of 2.30, it increased by 0.15 dollars. 

    Its percentage increase is thus 0.15/2.30  * 100 = [left for you].

    Hopefully no one will spoil you the answer thereby depriving you from your personal enhancement; that would be very inconsiderate of them.
