The question is incomplete. Here is the complete question
Suppose the demand for Digital Video Recorders (DVRs) is given by Q = 250 - .25p + 4pc, where Q is the quantity of DVRs demanded (in 1000s), p is the price of a DVR, and pc is the price of cable television. How much does the quantity demanded for DVRs change if the p rises by $40? A) drops by 10,000 DVRs B) increases by 16,000 DVRs C) drops by 2,500 DVRs D) increases by 4,000
Answer:
Drops by 10,000 DVRs
Explanation:
The demand for digital video recorders is expressed by
Q= 250- .25p+4pc
Where
Q represents the quantity demanded by the customers
P represents the price of DVR
pc represents the price of cable television
Since the factor of p in the expression above is negative, this implies that the quantity of DVR demanded in the market will reduce
If the price of DVR increase by $40, then the quantity demanded will reduce by
= 0.25×40×1000
= 10×1000
= 10,000 units
Hence the quantity of DVRs drops by 10,000 DVRs if the price is increased to $40
