How much is around trip ticket from Philadelphia to Hartford from the 22 to the 25th one adult

I only paid $35 for one way ticket from Hartford to Boston for through Greyhound so I'm guessing around trip is maybe between 40 to 45 bucks

I cannot guarantee what days and time but I know from Hartford Connecticut to Philadelphia about a $207 is 172 to go down 72 or 73 to come back to Hartford or vice versa. But the whole trip should be no more than 210 unless the prices went up of course I get off at 30th Street train station in Philadelphia
