Answer: 19.5 gallons

Explanation:

Hi, to answer this question, we have to use proportions:

Nathaniel buys 28 gallons of gas for $56, so the proportion is:

$56 / 28 gallons.

For $39:

$39 / x gallons

Solving for x (number of gallons)

56/28 = 39/x

x = 39 / (56/28)

x = 19.5 gallons

Feel free to ask for more if needed or if you did not understand something.
