Question

The price of gasoline purchased varies directly as the number of gallons of gas purchased. Suppose 19 gallons are purchased for $22.50

Answer 1

Missing Part:

What is the price of purchasing 14 gallons?

Answer:

14 gallons cost $16.58

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 = (\$315)/(19)`

`x = \$16.58`
