In 2012, germans paid 1.65 euros per liter of gasoline. at the same time, american prices were $3.90 per gallon. a. how much would one gallon of european gas have cost in dollars? b. how much would one liter of american gasoline have cost in euros? (one us dollar = 0.76 euros, 1 gallon = 4.55 liters)

Germans paid 1.65 euros per liter of gasoline

American prices were $3.90 per gallon and for one liter = $3.90 / 4.55 = $0.86

One US dollar = 0.76 Euros

If Germans paid 1.65 euros for 1 liter, they will pay for 1 gallon = 1.65 euros x 4.55 liters = 7.51

Price of one gallon Germans paid in euros = 7.51 euros

As, 1 Us dollar=0.76 euros from this we get 1 euro = 1.31 dollars

So, price of one gallon Germans paid in dollars = 7.51 x 1.31 = $9.84

American gasoline have cost in euros per liter = 0.86 x 0.76 = 0.65 euros
