What percentage of a power bill would you think is a/c and heat (in FL) sm

My electricity bill averages $150 per month. I run normal lights, a/c full-time during the summer, heat off and on in the winter (N FL), dishwasher 3 times a week, dryer about 5 hours a week, and 3 computers. Would $50 per month be about right for the A/C and heat portion?

Don't ask why I'm asking this... just figured out the utilities portion of the home office think on schedule C (posted below in reponse to another post).
