At a price of $4.69 per pound, the supply for cherries is 16,210 pounds, and the demand is 10,280 pounds. When the price drops to $4.22 per pound, the supply decreases to 10,940 pounds and the demand increases to 12,746 pounds. Assume that the price-supply and price-demand equations are linear. What is the equilibrium quantity? Round to the nearest pound. pounds.

Consider the supply of nails shown in Figure 2. The initial supply of nails is S (in black), the initial price of a pound of nails is $12, and the initial quantity supply of nails is 40K pounds. Which of the following correctly describes the effect of a decrease in the supply of nails while the price of a pound of nails remains at $12?        A) The supply curve shifts left to S'' (in red), and the quantity supply of nails decreases to 25K pounds.       B) The supply curve remains at S (in black), and the quantity supply of nails remains at 40K pounds.       C) The supply curve remains at S (in black), and the quantity supply of nails decreases to 25K pounds.       D) The supply curve shifts left to S'' (in red), and the quantity supply of nails remains at 40K pounds.

6) The quantity demanded of a certain brand of smart phone is 2000 per week when the unit price is $84. For each decrease in the unit price $5 below $84, the quantity demanded increases by 50 units. The supplier will not market any of the smartphones if the unit price is $60 or less, but the supplier will market 1800 per week if the unit price is $90. The supply and demand equations are known to be lineara) Find the demand and supply equationsb) Find the equilibrium quantity and price

Question 20 The following diagram illustrates the impact of an increase in demand. Which of the following statements is INCORRECT? R12 R11 R10 900 1000 1 100 1 200 1300 a) Before the increase in demand, the equilibrium price is R10 and the equilibrium quantity is 900. b) Owing to an increase in demand, the demand curve shifts from D to D1. At a price of R10, after the increase in demand, the quantity demanded is 1 200 and the quantity supplied is 1 100. c) At a price of R10, after the increase in demand, there is an excess demand. d) A new equilibrium position is formed after the increase in demand at an equilibrium price of R12 and an equilibrium quantity of 1 100.
