You are trying to decide which of two automobiles to buy. the first is american-made, costs $3.0500 x 104, and travels 22.0 miles/gallon of fuel. the second is european-made, costs $4.9100 x 104, and travels 17.0 km/liter of fuel. if fuel costs $2.50/gallon, and other maintenance costs for the two vehicles are identical, how many miles must each vehicle travel in its lifetime for the total costs (puchase cost fuel cost) to be equivalent?
