You buy some beads and string from a student on campus to make a bracelet for yourself. You valued the materials at $9 but were charged only $8. Unknown to you, the seller would have sold them for $5.

You are thinking about renting a room in a house next year with three of your friends. For each month’s rent, you are willing to pay $580, your first friend is willing to pay $550, your second friend is willing to pay $560, and your third friend is willing to pay $610. The landlord agrees to offer each of you separate leases but will charge you all the same price: $550.
You decide this is a good deal, so you and your friends move in. A couple of months later, you learn from someone who knows the landlord that he would have been willing to rent each room for $500 per month.

Monthly sales of a particular brand of spirits at one store have pre-tax demand curve D1. A new state alcohol tax is enacted, leading to the store's post-tax demand curve D2. The tax is assessed at the point of sale as a tax on buyers.
Use the area tool to draw the area representing the deadweight loss that is due to the tax, clicking on the three corners of the area. 

What deadweight loss results from the tax?

Monthly sales of an herbal supplement at one store have pretax demand curve D1. A new state tax on this herbal supplement shifts the post-tax demand curve to D2. The tax is assessed at the point of sale as a tax on buyers.
Use the area tool to draw the area representing the state's monthly tax revenue from this one store's sales of the taxed herbal supplement. Your drawing should be a rectangle created with four corners.
