Question
2. The demand and supply functions of a gcod are given by P = -Qd + 125, 2P =
3Qs + 30. Determine the equilibrium price and quantity. Determine ako the effect on
the market equilibrium if the govemment decides to impose a fixed tax of GHC5 on each
good Who pays the tax? (p = 81, q = 44, then p = 83, q = 42)
3. If fixed costs are 18, variable costs per unit are 4, and the demand function is P = 24 -
2Q. Obtain an expression for n in terms of Q and hence sketch a graph of n against Q.
a) For what values of Q does the firm break even? (q = 1 or 9)
b) What is the maximum profi? (n = 32 at q = 5)
4. Given the supply and demand functions
P = Q? + 12Q, + 32,
P = -Qå - 4Qa + 200,
Calculate the equilibrium price and quantiy. (p = 140, q = 6)
