Stella is a single taxpayer and operates a self-employed business that provides pet-sitting services. The business is considered a sole proprietorship for income tax purposes and represents Stella's only source of income. In 2018, the standard deduction amount was greater than Stella's total itemized deductions. Stella does not have any available tax credits nor did she make any estimated tax payments for her 2018 tax return.

Stella reports her income and expenses from the business using the cash method. Stella's automobile was used partially for business use and partially for personal use. She uses the IRS' optional standard mileage rate to compute her car expenses related to the business.

Stella has retained contemporaneous documentation for all cash receipts and disbursements and uses an app on her phone to accurately track her business-related mileage. She has summarized the results in the table below:

1. How much net profit will Stella report on her 2018 Schedule C, Line 31?

2. What is Stella's 2018 adjusted gross income ("AGI") that will be reported on Form 1040, Line 7?

3. How much tax will Stella owe on her 2018 Form 1040, Line 22? Hint - her taxable income falls within the lowest tax bracket; therefore, her regular tax liability is simply 10% of taxable income.
