If the demand is inelastic
%↓in P>%↑in Qt
loss in total revenue>gain in total revenue
thus,the total revenue would decrease.

其實有無咩方法可以更容易知道 elastic既出現呢,
老師沒有什麼太大提到....
仲有...
對於elastricity,
可以唔以講下long -run下面既野,
好似有d野叫咩economies of scale等三個分支?

雖然elasticity會出現係會考...
不過多數都係出係畫圖方面
頂多問你個producer既有冇gain或loss...呢種就關elasticity事
我就冇咩點溫呢課..
順帶一提.....上面好似冇人串對elasticity一字-.-
