You ultimately want to know cost per kW-hr, but let's start with what we know. The MP3 player uses 3 W and one battery lasts 2 hours. The voltage, in this case, is irrelevant. One battery provides 6 W-hr (3 W times 2 hours) and costs $0.50. That's $0.50 per 6 W-hr or $.0833/W-hr. If you want it in kW-hr, multiply by 1000 to get $83.3/kW-hr, which incidentally, is about 10 times more than paying for electricity from the wall.
