The Wall Street Journal reported that the Chinese government is planning to adopt more stringent automobile fuel efficiency standards to keep oil consumption in check. The standards vary depending on the type of vehicle. An SUV is required to get 17 mpg (miles per gallon). Medium weight passenger cars are required to get 25 mpg, and lighter passenger cars are required to get 33 mpg. If Ford Motors-China last year sold 138,000 SUVs, 291,000 medium weight passenger cars, and 482,000 light passenger cars in China, and all met precisely the fuel efficiency standards described, what was the average mileage for the total fleet of vehicles sold by the company?
