Answer 1

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

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

$x = \ 16.58$
