I would pay $80 a month and take the train to work. Taking my car to work would be faster but it would cost me $240 a month. Since I am a student it would be in my best interest to save my money and since this is a new job have something to fall back on if I get fired.
Taking the train to work will be longer but it will teach me to be disciplined in getting up on time. And, if I earn enough money to have a car, still have money to fall back on, and not worry about getting fired I will make a good impression on my employers and co-workers.
That is why I would choose to take the train to work. It will save money, I will learn to become more disciplined and I will always have a plan B if I get fired.
