Answer:
$12.47
Step-by-step explanation:
Given;
Demand = Qd = 1100 - 20p .......................................... (1)
Market supply = Qs = - 230 + 40p ..............................(2)
The subsidy of $1.10 by the govern will increase the price of the producers by $1.10 and Qs in equation (2) becomes:
Qs = - 230 + 40(p + 1.10)
Qs = - 230 + 40p + 44
Qs = -186 + 40p ....................................................................(3)
At equilibrium, Qd = Qs. Equating equations (1) and (3) and solve for equilibrium price p, we have:
110 - 20p = -186 + 40p
110 + 186 = 40p + 20p
296 = 60p
p = 296 / 60
p = 4.93
Substitute p into equation (3) to obtain equilibrium quantity, Q, we have:
Qs = -186 + 40(4.93) = 11.33
Cost of subsidy to taxpayers = Qs * Subsidy per unit = 11.33 * 1.10 = $12.47.
