JNU SIS 2015 Question 26: Perfect competition

Suppose the supply of apples is given by S=(10+4P)S = (10 + 4P)S=(10+4P) and the demand for apples is given by D=(100−6P)D = (100 - 6P)D=(100−6P). Suppose the government institutes a subsidy of t=$3t = \text{\textdollar}3t=$3 per unit of apples sold. Calculate QQQ, the equilibrium quantity of apples sold after the subsidy is imposed and RRR, the tax revenue needed to pay for the subsidy.

Plain-text version

Suppose the supply of apples is given by S = (10 + 4P) and the demand for apples is given by D = (100 - 6P). Suppose the government institutes a subsidy of t = $3 per unit of apples sold. Calculate Q, the equilibrium quantity of apples sold after the subsidy is imposed and R, the tax revenue needed to pay for the subsidy. (A) Q = 46, R = 138 (B) Q = 50, R = 150 (C) Q = 53· 2, R = 159· 6 (D) None of the above
