According to the diagram, what is the dollar amount of the unit tax? a$0.00 b$0.45 c$0.55 d$1.00 e$1.45

Without access to the diagram mentioned, I can't provide a specific answer regarding the dollar amount of the unit tax. Typically, the diagram would contain crucial information such as demand and supply curves, price points, or any shifts that indicate the amount of tax.

To determine the unit tax amount:

1. Examine the Diagram: Look for the vertical distance between the supply and demand curves at the equilibrium point post-tax implementation.
2. Identify Key Points: Note the prices before and after the tax is applied to find the difference.
3. Calculate the Unit Tax: The difference between these two prices will give the unit tax amount.

If you can provide additional details or describe the diagram, I would be glad to help you analyze it.
