我想問下幾時要+埋supply curve落個graph度???
姐係咁,,,成日見到d pastpaper得demand curve但係明明 supply 無變到佢個marking scheme都無畫埋落去.??點解?
好似2005 ce section B Q9a咁
The western harbour crossing has no traffic congestion problem. IN july2004,its tolls increased.
(a)with the aid of a diagram,,explain under what condition an increase in the tolls would increase the sales revenue of the tunnel company.
點解ans無畫埋supply curve???
咁其實幾時先要畫??
百萬個感激=)
