Answer:
26 Miles
Explanation:
As per IRS,
Commuting is a personal nature of expense, which is not allowable as deduction.
The following things are not deductible for Greg:
(i) Distance traveled from office to home and home office is not deductible.
(ii) At the end of day, 7 miles distance traveled towards home from Martin's dry cleaning is not deductible.
Deductible includes the miles traveled to the business sites from the office for Greg.
Therefore,
Deductible transportation miles:
= Distance traveled from office to smith's house + Distance traveled from smith's house to martin's dry cleaning
= 5 miles + 21 miles
= 26 Miles
