Excise taxes are fixed and included in the price of the product or service. What type of tax would this be? a Proportional tax b Regressive tax c Progressive tax d Flat Tax

## Step 1<br />The problem is asking us to identify the type of tax that is fixed and included in the price of the product or service. This is a characteristic of a proportional tax.<br /><br />## Step 2<br />A proportional tax, also known as a flat tax, is a tax where the tax rate is fixed and does not change with the amount subject to taxation. This means that the tax rate is the same for all taxpayers, regardless of their income or the value of the goods or services they are purchasing.<br /><br />## Step 3<br />In contrast, a regressive tax takes a larger percentage of income from low-income earners than from high-income earners. A progressive tax takes a larger percentage from high-income earners.
