Using proportions, it is found that the equivalent cost in U.S. dollars per gallon would be of 5.11.
<h3>What is a proportion?</h3>
- A proportion is a fraction of total amount, and the measures are related using a rule of three.
In September 2016, the cost of gasoline in Berlin was around 1.21 euros per liter. Hence, per gallon, that is, per 3.785 liters, we use a rule of three to find the cost.
1.21 euros - 1 liter
x euros - 3.785 liters
Applying cross multiplication:
Cost of 4.57986 euros per gallon. Since 1 U.S dollar is equivalent to approximately 0.896 euros, we have that:
1 dollar - 0.896 euros
x dollars - 4.57986 euros
Applying <em>cross multiplication</em> again:
The equivalent cost in U.S. dollars per gallon would be of 5.11.
