While in Europe, if you drive 107 per day, how much money would you spend on gas in one week if gas costs 1.10 per liter and your car's gas mileage is 42.0 ? Assume that 1 euro=1.26 dollars
assuming you meant 107km/day, then to convert km to euros,
107km/day * 1L/42km * 1.1euro/L = 2.80 euro/day
your units are ambiguous.
Is gas 1.1 euros/liter. or 1.1 dollars/liter?
Do you want the final answer in dollars, or euros?
As long as you're ambiguous, is "mileage" in miles/gallon, or km/liter?
Whatever the answers, use my calculation as a model for further conversions.
