To determine the type of tax being described, we can analyze the income tax payments of Pugsly and Wednesday relative to their incomes.
- Pugsly earns $50,000 and pays $5,000 in taxes, which is 10% of his income.
- Wednesday earns $70,000 and pays $7,000 in taxes, which is also 10% of her income.
Since both individuals pay the same percentage of their income in taxes, this situation represents a proportional tax system, where the tax rate is the same regardless of income level.
Therefore, the correct answer is proportional tax.
