If the price of gasoline in Germany is about $1 per liter, what is the equivalent price of gasoline in dollars per gallon?
I know that
1 gallon =3.79 liter
l liter= 0.26 gallon
but I am not sure how to figure the cost?

$1.00 * 3.79 = ?
You must have an old book. The current German price of gasoline per gallon is $7.08.

1 litre costs $1
so 3.79 litres cost $3.79
but 3.79 litres = 1 US gallon
so it costs $3.79 per gallon
(BTW, it is much more expensive than that in Germany.
They are currently paying about $7 per US gallon)

Heh, Ms. Sue and I found exactly the same webpage!
What a coincidence. 
Ms. Sue that's public schools for ya!
Thank you both for your help!!! 
Home schoolers seem to have even older books. <g>
You're very welcome. 
A gas station purchases gasoline from a refinery at the unit price of $3.20 per gallon and sells it to their customers at $3.68 per gallon.
What is the percent markup?
