Not sure how you came up with 5 cents but I get $1.36:
4000 dollars/btc * 10^-8 btc/satoshi * 150 satoshi/byte * 226 bytes/transaction = $1.356 per transaction
If you wanted to get confirmed in the very next block you could probably use 25 satoshi/byte at this point in time. Personally, if I were sending a non critical/time-sensitive transaction right now I would use about 5 satoshi/byte.
