    Percentage increase can be found by the following equation:

    (new cost / old cost) - 1 = percentage increase

    Plug the values in.

    (2.80/2.45) - 1 = percentage increase

    1.1428 - 1 = 0.1428

    Convert the decimal to a percentage.

    0.1428 = 14.28%

    Rounded to the tenth spot, the percentage increase is 14.3%.
