Following relations describe monthly demand and supply for computer support service catering to small businesses. Qd= 3000-10P and Qs=-1000+10P, Q is number of business that needs services and P is the monthly fees in dollars Q1: At what average monthly fee would demand be equal to zero (O)? Q2. At what average monthly fees supply would be equal to zero (0)? Q3. Plot the supply and demand curves Q4. What is the equilibrium price and output levels? Q5. Suppose demand increases to Qd=3500-10P, what is the effect on supply, what are the new equilibrium P and Q (compare this P and Q with previous equilibrium P and Q when demand function was Qd = 1000+10P). Q6. Suppose new suppliers enter the market due to increase in demand, so that new supply curve is Qs=-500+10p. What are the new equilibrium price and quantity
