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:
[tex]19 ----------> \$22.50[/tex]
[tex]14 ----------> x[/tex]
Cross Multiply:
[tex]19 * x = 14 * \$22.50[/tex]
[tex]19x = \$315[/tex]
Solve for x
[tex]x = \frac{\$315}{19}[/tex]
[tex]x = \$16.58[/tex]
