15kg of butane is 20.99
http://en.wikipedia.org/wiki/Butane
Molar mass 58.08 g/mol
Density 2.52 g/l, gas (15 °C, 1 atm)
425 and 411 kJ/mol for the two types of C-H bonds of energy with that and some stoichiometry you should be able to work out a cost ber Kw of the gas in that bottle. I would imagine it will be more than 10.5p/Kw though.
