a. What is the equilibrium price of hot dogs? What renders you think so? According to the definition, the equilibrium price is the price at which quantity gave amounts to quantity demanded. From the table we have the right to view that at $1.60, Qs = Qd = 2,400. Therefore $1.60 is the equilibrium price.

b. If the organizers of the sporting event decide to collection the price at 1.80, how many type of hot dogs will be sold? At $1.80, 4,800 hot dogs will be available for sale, however just 1,600 will certainly be demanded. Thus, just 1,600 hot dogs will certainly be offered.

4. The full demand for wwarm and also the full supply of wheat per month in the Kansas City grain sector are as follows:

a. Market equilibrium occurs at the suggest wbelow industry clears, that is, where amount provided is equal to amount demanded. In various other words, equilibrium price is the price at which tright here exists neither surplus nor shortage. Looking at the entries in the last column (in bold), we have the right to check out the equilibrium price is $4. As such, the equilibrium amount is 75,000 bushels.

b. For your individual job-related.

c. At $3.40, tright here would certainly be a 13,000 bushels shortage of wwarm. The price will not continue to be at that level considering that it will be in the sellers" finest interest to raise their prices. At $4.90, sellers will certainly supply 21,000 bushels more than buyers would demand, hence developing a excess. In order to get rid of the surplus, sellers would have to decrease their price.

d. The statement is false. A excess indicates that at a offered price, amount supplied is higher than quantity demanded. Trying to get rid of the surplus, sellers will certainly decrease their prices. Because of this, surpluses drive prices down, not up. Shortages, on the various other hand also, give sellers the opportunity to raise prices, for this reason "shortperiods drive prices up".

e. A ceiling at $3.70 establimelted by the government (which more than likely tries to proccasion the price from being what it perceives as "too high") would not permit the price to move in the direction of the equilibrium. As a result, a irreversible shortage of wwarmth will certainly emerge. Buyers will demand 7000 even more bushels of wwarmth than tright here is accessible.
