Question 2
A monopolist faces a demand curve given by the equation Qd = 100 - 2P. If the firm's marginal \cost (MC) is cons\tant at ₦20 per unit, what is the likely effect on the firm's profit-maximizing price and output level if the government imposes a tax of ₦5 per unit?

Question 3
A government imposes a tax of ₦5 per unit on a good. The demand for the good is given by the inverse demand function \( p = 100 - 2q \), where (p) is the price and (q) is the quantity demanded.

A. ₦200, 50 units
B. ₦300, 75 units
C. ₦400, 100 units
D. ₦500, 125 units
Question 5
The government of a country imposes a subsidy on a particular good, which decreases the price of the good by 15%. If the supply of the good is given by the equation Qs = 100 + 2P, where Qs is the quantity supplied and P is the price, what is the new supply equation after the subsidy is imposed?
A. Qs = 90 + 2P
B. Qs = 95 + 2P
C. Qs = 105 + 2P

The production function for good X is given by Qx = 10L^0.5K^0.5, where Qx is the quantity of good X produced, L is the amount of labor used, and K is the amount of capital used. If the price of good X is ₦100 and the price of good Y is ₦200, and the firm's budget constraint is 100L + 200K = ₦1000, what is the optimal combination of labor and capital that the firm should use?

C. L = 20, K = 2
D. L = 15, K = 3
Question 9
A firm's average \cost curve is given by \( AC = \frac{100}{x} + 10 \), where ( x ) is the number of units produced. If the firm produces 20 units, what is the average \cost?
A. ₦5
B. ₦10
C. ₦15
D. ₦20
Question 10
A firm's \cost function is given by C(x) = 100 + 2x^2, where x is the number of units produced. If the firm produces 10 units, what is the total \cost?
A. ₦200
B. ₦220
C. ₦240
D. ₦260
Question 11
A government's budget constraint is given by G = T + I, where G is government exp\enditure, T is tax revenue, and I is interest payment. If the government's tax revenue is ₦100, interest payment is ₦50, and government exp\enditure is ₦150, what is the budget deficit?
A. ₦50
B. ₦100
C. ₦150
D. ₦200
Question 12
A firm's demand curve is given by Q = 100 - 2P. The firm's supply curve is given by Q = 2P. Find the equilibrium price and quantity.
A. ₦200, 50 units
B. ₦300, 75 units
C. ₦400, 100 units
D. ₦500, 125 units
Question 13

B. Decrease its quantity supplied
C. Increase its quantity demanded
D. Decrease its quantity demanded
Question 14
Consider a country with a perfectly competitive market for a particular good. The demand for this good is given by the inverse demand function \( p = 100 - 2q \), where (p) is the price and (q) is the quantity demanded.
