If I have a demand curve on Q=70-0.5P, and development and coding are approx $2,350 (*fixed costs?*), and the constant cost per unit is $12:

1.) How many copies should I attempt to sell and at what price? What would be the profit.

2.) What quantity and price will result once competing software emerges? How much consumer surplus will my clients (lawyers) gain once the competitors enter?

3.) How much deadweight loss is created by my patent and monopoly in this software?
