Step-by-step explanation:

We pay $14 for 4 gallons, so if we split the $14 in 4 equal parts we will know how much we pay for 1 gallon ( the unit price.)

Then if we know the price we pay, like $7, we can see how many gallons we have because we know the unit price.

Then if we know how many gallons we have, we can see how much we have to pay because again we know the unit price.
