    Missing Part:

    What is the price of purchasing 14 gallons?

    Answer:

    14 gallons cost $16.58

    Step-by-step explanation:

    Given

    Gallon —- Price

    19 ———- $22.50

    Required

    Determine the price of 14 gallons?

    Represent this price with x

    Since, it is a direct variation. The table can be completer as thus:

    19 ----------> \$22.50

    14 ----------> x

    Cross Multiply:

    19 * x = 14 * \$22.50

    19x = \$315

    Solve for x

    x = \frac{\$315}{19}

    x = \$16.58
