Question

Gasoline at a particular gas station costs $2.78 per gallon. If Cory buys $18 of gas, how many gallons did he buy?

Answer 1

Answer:

Cory bought 6.474 gallons of gasolline.

Step-by-step explanation:

The total cost of gasoline ($C$), measured in dollars, is given by the following expression:

$C = n\cdot c$

Where:

$n$ - Amount of gasoline, measured in gallons.

$c$ - Unit cost, measured in dollars per gallon.

Given that $C = \ \,18$ and $c = \ \,2.78\,\frac{1}{gal}$, the amount of gasoline is cleared and calculated:

$n = \frac{C}{c}$

$n = \frac{\ \,18}{\ \,2.78\,\frac{1}{gal} }$

$n = 6.474\,gal$

Cory bought 6.474 gallons of gasolline.
