While in Europe, if you drive 125 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 39.0 mi/gal? Assume that 1euro= 1.26; dollars.

First convert 1 day to 7 days since it equals a week
125km x 7= 875km
then convert km into mi
875km x 0.6214mi/1km = 543.725mi
then convert miles to gallons
543.725mi x 1gal/31.0mi = 17.54gal
then convert gallons to Liters
17.54gal x 3.79L/1g = 66.40L
then make it into euros
66.40L x 1.10 euros = 73.03 euros
and finally convert to dollars
73.03 x 1.26 = $91.9
