doesn't matter how many miles they drove. That's just noise, unless you have to figure their gas mileage.
On conversion problems like this, it's important to recall that you can always multiply by 1 and not change anything. The trick is to keep track of the units, so they cancel out properly, leaving you with what you want.
You want to convert dollars to gallons. The conversion factor is
1gallon/$3.20
That is just "1" with the proper units.
1 gallon = $3.20
1gallon/$3.20 = 1
So,
$377.60 * 1gal/$3.20 = 377.60/3.20 gal = 118 gal
