A year later, you receive a $0.50 per share dividend and sell the stock for 27. What is your rate of return on the investment?
market consists of three people A, B and C whose individual demand equations are as follows:
A: P = 30 – 1.00QA
B: P = 30 – 1.33QB
C: P = 30 – 0.80QC
(i) What is the market demand equation?
(ii) If one has 60 units, what price should he charge to sell the entire units? Determine the quantity demanded from each market
(iii) If the industry supply equation is QS = 70 +2P, determine the equilibrium price and quantity.
ii) Write an SQL query that returns the titles of articles authored by 'Robert Tarjan'.
