Answer:
The correct answer is letter "D": Total mileage for each use would not include the mileage from the other business use.
Step-by-step explanation:
In case the same vehicle is used for two different businesses, for tax return purposes, the mileage used for each business must be separated and reported isolated in the tax return. The standard mileage rate method is used for this matter. The total mileage driven within the year cannot be entered as the one used for each business individually.
