Suppose you can write generic supply and demand curves such that $\mathrm { Q } _ { \mathrm { S } } = \mathrm { A } + \mathrm { BP }$ and $Q _ { D } = D + C P$ .In the usual supply-demand configuration,D must be.
A)positive
B)negative
C)0

Question

Quizplus · Accepted Answer

In the usual supply-demand configuration, the demand curve is downward sloping, meaning as price increases, quantity demanded decreases. Therefore, D must be positive to ensure that the demand curve has a negative slope when combined with a negative C.
