Final answer:
The question asking which worker had the lowest taxable income last year cannot be answered without specific data about the workers' incomes. Determining taxable income requires computing total income minus deductions and exemptions. No clear answer can be provided without additional income data for the individuals named.
Step-by-step explanation:
The question regarding which worker had the lowest taxable income last year cannot be answered without specific data about each individual's taxable income. Taxable income is typically determined by computing a person's total income and subtracting the allowable deductions and exemptions, resulting in the amount of income on which the individual will be taxed.
The statement provided offers a view on how reducing income taxes might enable people to earn more by taking home a larger portion of their wages. However, without numerical values or further context about Kevin, Louis, Madelyn, and Selma's incomes, it is impossible to determine which worker had the lowest taxable income. The question appears to be missing a critical part of the data.
If this was a real-life scenario, each worker's taxable income would need to be evaluated based on their gross income, applicable tax credits, deductions, and any other relevant financial information to ascertain who among them had the lowest taxable income.
