Answer :
6 books should change hands at the equilibrium price
An equilibrium price, also known as a market clearing price, is the agreed upon price when a product transaction takes place. When market supply and demand are in balance, prices become steady. This is known as equilibrium. In general, a surplus of goods or services leads to lower prices, which increases demand, whereas a shortfall or undersupply raises prices, which decreases demand. The coffee market is in a state of equilibrium. There won't be a propensity for pricing to move unless the supply or demand curves alter. In each market, the equilibrium price is the one where supply and demand are equal. Thus, $6 a pound is the market's equilibrium price for coffee.
