PhotoJournal sells royalty-free stock photographs on the Web. Home users are generally content with low-quality images for family newsletters. Professional users generally require high-resolution images suitable for commercial printing (though can make low-resolution images work with extra effort and editing). The unit cost of producing and delivering either version is zero. PhotoJournal estimates that:

Professional users value low-resolution images at $30 each and high-resolution images at $50.

Home users value low-resolution images at $20 each and high-resolution images at $25.

A. $40,000

B. $50,000
