A LOT OF POINTS!!!! Darnell's car used 8 gallons of gasoline to travel 340 miles. After a mechanic worked on the car, it used 7 gallons of gasoline to travel 350 miles. If the price of gasoline was approximately $4.00 per gallon, how much less, to the nearest cent per mile, did it cost to run the car after the mechanic worked on it? Please tell me the correct answer with the steps!! Whoever gives the answer with steps will be marked the BRAINLIEST!!!
