Question 8
The Nigerian government has implemented a policy to increase the production of rice in the country. The policy includes providing subsidies to farmers, improving irrigation systems, and increa\sing the supply of fertilizers. However, the policy has been criticized for being too expensive and for not addres\sing the root causes of the country's food insecurity. Which of the following is a potential consequence of the policy?
A. Increased rice production and reduced food prices
B. Increased rice production but no reduction in food prices
C. Decreased rice production and increased food prices
D. No change in rice production and food prices
Question 9
A firm's production function is given by Q = 100L^0.5K^0.5, where L is labor and K is capital. The firm's \cost function is given by C = 10L + 20K. What is the firm's profit-maximizing level of labor?
A. 10
B. 20
C. 30
D. 40
Question 10
The demand function for a product is given by \( Q = 100 - 2P \). If the supply function is \( Q = 2P - 10 \), what is the equilibrium price?
A. \( P = 5 \)
B. \( P = 10 \)
C. \( P = 15 \)
D. \( P = 20 \)
Question 11
A government imposes a tax on imports to reduce the trade deficit. However, the tax also increases the \cost of production for domestic firms. U\sing the concept of supply and demand, explain how the tax affects the equilibrium price and quantity of the good.
A. The tax increases the equilibrium price and decreases the equilibrium quantity.
B. The tax decreases the equilibrium price and increases the equilibrium quantity.
C. The tax has no effect on the equilibrium price and quantity.
D. The tax increases the equilibrium price and increases the equilibrium quantity.
Question 12

A. 200
B. 220
C. 240
D. 260
Question 13
A consumer's utility function is given by U = 2x + 3y, where x and y are the quantities of two goods consumed. If the consumer's budget constraint is 2x + 3y = 12, and the prices of the two goods are p_x = 2 and p_y = 3, calculate the consumer's optimal consumption bundle \( x*, y* \) and the maximum utility U*.
