Final answer:
Chinwe can reduce her taxes by deducting ordinary and necessary business expenses such as gas mileage, leashes and waste bags, doggie treats and toys, and advertisements. Personal clothing usually is not deductible unless it's a uniform, and a coffee machine typically isn't deductible as it may not be directly related to her business operations.
Step-by-step explanation:
Chinwe, as a business owner, can indeed reduce her taxes by deducting certain expenses that are ordinary and necessary for the operation of her dog walking business. These deductions can include a variety of costs. For example, gas mileage for traveling to client's homes can be deductible as a business expense. Similarly, leashes and waste bags are essential for the service she provides and are also deductible. Doggie treats and toys could be seen as a necessary expense for keeping the dogs happy and engaged, thus they too can be deducted. Advertisements are a crucial part of promoting her business and are fully deductible as a business expense.
However, there are items that typically cannot be deducted, like personal clothing, unless it is a uniform or has the business logo and is only used for work. Lastly, a coffee machine, unless used exclusively for the business and in a place of business, would not normally be considered deductible as it is not directly related to the dog walking business operations.
