While in Europe, if you drive 117 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 42.0 mi/gal? Assume that 1euro=1.26dollars.

Total Cost of Week = 81.20 Euros

Total Cost of Week (in dollars) = $102.31

Step-by-step explanation:

117 km per day

You drive 7 days

So,

Total miles driven = 117 * 7 = 819 km

Mileage is 42 miles per gallon. So how many gallons would it require to drive 819 km?

819/42 = 19.5 gallons

We know 1 gallons = 3.78 liters

So,

19.5 gallons would be:

19.5 * 3.78 = 73.82 liters

1.10 Euro PER LITER, so the total cost:

Total Cost of Week = 73.82 * 1.10 = 81.20 Euros

In dollars (1 euro = 1.26 dollars):

Total Cost of Week (in dollars) = 81.20 * 1.26 = $102.31
