#### Work Step by Step

To convert 2.50 dollars per liter to dollars per gallon, we need to multiply this amount by the ratio that converts liters to gallons.
The ratio that converts liters to gallons is $\frac{3.8\ liters}{1\ gallon}$.
So, $\frac{2.5\ dollars}{1\ liter}$ $\times$ $\frac{3.8\ liters}{1\ gallon}$ =
$\frac{2.5\ dollars\ \times\ 3.8}{1 gallon}$ =
$\frac{9.5\ dollars}{gallon}$ = 9.5 dollars per gallon
The price would be 9.5 dollars per gallon.
