求解 依課一向麻麻地 諗唔明 想有個詳細嘅logic flow 唔該哂
1. 搵equilibrium
Qd = Qs = 3 units at P=120
2. Effective Price Floor?
Yes, Pf = 130 > 120
3. Consumer Surplus
New CS = 10
Old CS = 20+10 = 30
4. Producer Surplus
New PS = 30+20=50
5. TSS new = CS+PS = 60
=> A
依兩part係點計出黎?邊個數減邊個數?
20 10 30同20依幾個數
同埋另外一位巴打講可以用(140-100)+(130-110)嘅方法計tss 兩個brackets係分別計緊cs and ps定點?
依課真係唔掂 等埋巴打解答拿拿聲溫番熟啲concepts先得
