Calvin lives in San Francisco and commutes to work. In the month of March 2014, he will be taking a direct bus to and from work on Mondays, Wednesdays and Fridays, and he will be driving to Oakland on Tuesdays and Thursdays. He can choose from several options of payment:

 *Pay $2 for each (one-way) trip.

* Pay $15 for a day pass

* Pay $29 for a week pass

* Pay $66 for a monthly pass

If Calvin doesn't use the bus otherwise, which option will be the cheapest for him?

March 2014 was like this

 

Had 5 mondays, 4 wednesdays, 4 fridays.

 

SO.

 

He must pay for 13 days.

 

Single pass... 26*2 = 52$

 

Thus single trip is the best.
