The cost of driving on a trip is the amount of money you need to pay
for gas and rental cars to go on a trip.
The equation for finding the cost of driving on a trip is:
 
COD = COG + COR
where
COD = Cost of Driving
COG = Cost of Gas
COG = # of Gallons used ´ Cost of Gasoline
per gallon
COG = (Distance/MPG) ´ Cost of Gasoline per
gallon
COR = Cost of Rental Car.

Eddie and his parents are planning to go on a vacation trip driving from Houston to
Orlando. They want to rent a midsize car at $250 per week. They’re going for 1.5
weeks. The roundtrip driving distance is 2,268 miles. The average gas mileage is 20 mpg.
Unleaded gas costs $1.359 per gallon. What is their cost of driving?
COD = COG + COR
COD = (2268/20)(1.359) + (250)(1.5)
COD = 154.1106 + 375
COD = 529.1106
COD = 529.11
The cost of driving on this trip is about $529
