Question

darnells'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 the gasoline was approximately $4.00 a gallon,to the nearest cent per mile,did it cost to run the car after the mechanic worked on it

Answer 1

if it is $4.00 per gallon then we need to find the price of 7 gallons.
7 * 4.00 = 28
so it costs $28 to travel 350 miles.
no to find the cost per mile, we need to divide.
350 / 28 = 12.5
so the cost to run the car per mile is $12.50
