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



$20.70



$18.55



$15.91

Respuesta :

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.

The amount that you save each month is half of the total tank value, $20.70.

How much do you save each month?

We know that a gallon of gasoline costs $2.76, and the tank holds 15 gallons.

Then to fill the tank, you need to pay:

15*$2.76 = $41.40

Now, you have two friends, and each of the friends pays one-quarter of a full tank per month, then you only pay a fraction of the total, which would be one-half.

($41.40)/2 = $20.70

The amount that you save is:

S = $41.40 - $20.70 = $20.70

So the correct option is the second one.
