Answer:
Sell 650 computers, each for a price of $1,000
Explanation:
I have provided the graph on the attachment below.
A positive demand shock is a shift to the right of the demand curve, in the graph, represented by D3.
In D3, the point of equilibrium intersects at $1000 price and at 650 computers, therefore, in a positive demand shock, the firm would produce 650 computers, and charge a price of $1,000.
