问题: 急译求高手

drive the car that gets better gas mileage whenever possible if you own more than one vehicle. if you drive 12500 miles a year, switching 10 percent of your trips from a car that gets 20 miles per gallon to one that gets 30 mpg will save you more that $65 per year.

解答:

如你有不止一辆车,尽可能选油耗相对更低的开。如你每年行驶12500英里,有十分之一的里程是将每加仑20英里的车换成每加仑30英里的车,那么能使你每年省65美元以上。
