Alright, so to get across the tracks to my job at wanda's chicken waffle house, I got to drive like 3 miles. My car is a cadillac suv that my sugar daddy jamal gave me (haaaiii!!) that probably uses a lot of gas right? Plus I take some time to go to the mkdonalds drive thru, which is probably like another 10 miles. So if gas averages at like $3 a gallon (or $25 a litre), how much do I save if I take the bus which is like 2 bucks a trip? I need to know if it's worth it!!

Ok first off, it's spelt "transportation", just to help you for the future. That out of the way, your question is impossible to answer because you haven't given us your suv's gas mileage. If you could provide that, I could help you out maybe

No I think you're inaccurate.

$3 per gallon, or $2 for 10 miles. The two are equal if you can go 10 miles on $2 of gas, which is 2/3 of a gallon. 2/3 of a gallon in 10 miles would be 15 miles per gallon. If you get better, the car is a better deal; otherwise, the bus. Of course this ignores a great many factors like the cost of maintenance and insurance, the value of driving (at the same price, most would prefer to drive than take the bus), the cost of parking, the extra time needed to take the bus, etc.
