Joe's search costs are $5 per search. he wants to buy a video player for his wife for christmas, and the lowest price he's found so far is $300. joe thinks 80 percent of the stores charge $300 for video players and 20 percent charge $200. joe's optimal decision is to: continue to search for a lower price since the expected benefit of an additional search is $20, which exceeds his per-unit search costs. stop searching and purchase a video player for $200. continue to search for a lower price since the expected benefit of an additional search is $80, which exceeds his per-unit search costs. none of the statements is correct.
