Taxpayers with an office in their home may deduct a percentage of their home-related expenses. This percentage is based on the ratio of the office's area to the area of the home. A taxpayer with a 2200-square-foot home maintains a 10-foot by 19-foot office. If the yearly electricity bills for the home come to $4800, how much of
this is deductible?
How much money is deductible from the bill?
