Final answer:
Without additional context, the total tax Jane is responsible for paying cannot be identified from the provided choices. To calculate taxes, one applies tax rates to taxable income or uses a given tax table. The provided information is insufficient to determine Jane's tax obligation among the given multiple-choice options.
Step-by-step explanation:
The main answer to the question regarding the total tax that Jane is responsible for cannot be directly determined from the provided information. However, to solve a question like this, one would typically use the information from a tax table or a given tax rate. For instance, if Jane's taxable income were $20,000, then, using the provided example, her tax would be calculated as $837.50 + 0.15 × ($20,000 - $8,375), resulting in a total of $2,581.25. The answer would be selected from the provided multiple-choice options based on this calculation. However, none of the options match the computed value, so we must conclude there isn't enough context to give a correct answer from the provided choices A, B, C, and D.An explanation of how to handle sales tax and tips is to first calculate the amount of sales tax by applying the sales tax percentage to the pre-tax cost of an item or service.
