1. The problem asks: How much did I pay in tax? 2. To find the tax paid, we need to know the total amount paid and the tax rate or the pre-tax amount and the tax rate. 3. The formula to calculate tax paid is: $$\text{Tax Paid} = \text{Total Amount Paid} - \text{Pre-Tax Amount}$$ or if you know the tax rate and pre-tax amount: $$\text{Tax Paid} = \text{Pre-Tax Amount} \times \text{Tax Rate}$$ 4. Without specific numbers for total amount, pre-tax amount, or tax rate, we cannot calculate the exact tax paid. 5. Please provide the total amount paid and either the pre-tax amount or the tax rate to calculate the tax paid.
