I am turning to the Otter to try to answer a question.

I am in need of an average monthly cost in U.S. Dollars to heat the following:

720 sq. ft. one-level structure

Average outside temperature of 20 degrees F

Indoor temperature averaged at 50 degrees F

Natural Gas Heater operating at 70% efficiency

$9.99 per MCF

Let's assume that the windows and doors have little leakage from drafts, and that the structure is insulated.

I don't need an exact monthly dollar amount just something approximate based on the above info.

I'm horrible with math and the above are the only variables that I have.

Thanks in advance for pondering this for me.
