I believe the main reason is access to resources in case something goes wrong. Everything is open so medical emergencies can be treated easier without having to wake personnel.

Why are lampshades cone shaped?
I thought the lampshades were cone shaped to funnel light around a reading area or to dim the light source. But lampshades can be stacked when they are shipped reducing the cost of transportation which is 80% of the cost.
As always, your preferences are formed by some economist cutting costs somewhere.

How come you don't see head lettuce as much these days?
When shoppers want lettuce, they must accept the lettuce packaged and at a higher cost. Stores noticed that only perfect heads were selected. To increase sales, stores started marketing the lettuce in bags. Now they sell more lettuce and moving the lettuce to the store and storage is now less costly. Overall the higher price paid is worth it since there's less waste.

I skip over this topic since it's rarely tested on the AP. Instead, I made a teaching worksheet and saved it as a Google Document in pdf form so my students can still get the information. I plan to add consumer equilibrium in the future.
