in october 2007, one euro was worth $1.42. the price of gas in switzerland was .85 euros per liter. what was the cost in dollars per gallon?

Answer 1

1 euro = $1.42

0.85 euro = x

Cross multiply: x = $1.42 x 0.85 = $1.207 ~ $1.21 per liter

1 gallon = 1.378541 liter

$1.21 x 1.378541 = $1.688 ~ $1.70 per gallon
