$1.51

Explanation:

First, let's write an equation in fraction form where terms are similar; gallons on top, dollars on the bottom.

(5gallons)/($7.54) = (1gallon)/(x)

Now all we have to do is cross multiply

(5 gallons) * (x) = (5gallons)x

($7.54) * (1 gallon) = $7.54

This leaves you with $7.45 = (5gallons)x

Assuming x is in terms of USD, you can divide ($7.45)/(5gallons)

x = ($1.508)/(1 gallon) = ($1.51)/(1 gallon) (rounded)
