Answer:
Consumer surplus = (60000 - 40000)+ (90000 - 40000)+(40000 - 40000) = $70000
Producer surplus = (40000 - 20000)+(40000 - 30000)+ (40000 - 40000) = $30000
Social surplus = Consumer surplus +Producer Surplus= 70000 + 30000 = $100000
Consumer surplus = (Willingness to pay – Price)
Producer surplus = ( Price –Cost)
