來源: (例如: 90政大經濟系)
問題:General Motors estimates that U.S. demand for its newest product will
be: Qus=30,000-0.5P. Export demand will be Qex=25,000-0.5P.
The total market demand will be a
(A)straight line with a slope -0.5
(B)straight line with a slope -1.0
(C)kinked line with the kink at Q=25,000
(D)kinked line with the kink at P=50,000
答案為D，這題計算我不知道怎麼算，我想應該是兩個函數相加
不過算了很久還是都沒有選項的答案... 謝謝~~
