Answer:
[tex]11.79\ euros[/tex]
Step-by-step explanation:
The complete question is
Suppose that a new fuel-efficient European car travels an average of 28 kilometers on 1 liter of gasoline. If gasoline costs 1.50 euros per liter, how much will it cost to drive 220 kilometers ?
step 1
using proportion
Find out the number of liters of gasoline needed for 220 kilometers
so
[tex]\frac{28}{1}\ \frac{Km}{L}=\frac{220}{x}\ \frac{Km}{L}\\\\x=220/28\\\\x=7.86\ L[/tex]
step 2
Find the cost to drive 220 kilometers
Multiply the cost of one liter of gasoline by the total liters of gasoline needed to travel 220 Km
so
[tex]1.50(7.86)=11.79\ euros[/tex]
