6. Competition among sellers
A binding floor prevents sellers from cutting price. What margins does their competition move to instead?
7. The excess supply
Under a price floor of 30 dollars, quantity supplied is 90 jars and the demand curve is Qd = 120 - 2P. Compute the unsold surplus in jars and write the number.
