You can put this solution on YOUR website! begins the trip with 14 gallons of gas in her car.
The car uses up one gallon of gas every 30 miles.
Let g represent the number of gallons of gas she has left in her tank, and let d
represent the total distance (in miles)
:
d = 30(14 - g)
:
For example, if she uses two gallons, there will be 12 gal left in the tank; g=12
d = 30(14 - 12)
d = 30(2)
d = 60 mi
