Your parents allow you to borrow a car to get to your part-time job, but you have to pay for a tank of gas each month. Gasoline
costs $2.76/gallon and the tank takes 15 gallons. You have 2 coworkers who are each willing to pay for a quarter of a tank each month to carpool with you to work. How much do you save each month? $16.46
Step one is to take 2.76 x 15. That will give us the total cost. That is 41.40. Next, we need to divide 41.40 by 2. So in total, it will save you 20.70.
