问题: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
答案为D，这题计算我不知道怎麽算，我想应该是两个函数相加
不过算了很久还是都没有选项的答案... 谢谢~~
