Answer:

The correct answer is option A.

Explanation:

The demand for Digital Video Recorders is given as Q = 250 - .25p + 4pc.

Here,

Q is quantity demanded of video recorders and p is the price.

The quantity is represented in 1000 units.

And, pc is the price of cable television.

The coefficient of p is negative which means that as p increase Q will decline.

So when p increases by $40, Q will decline by

= [tex]0.25\times\ 40\times 1,000[/tex]

= 10,000 units
