Shamefully, the SAT has never given Maria Sharapova's contributions to higher mathematics due credit. The BSAT repairs that injustice with today's Math problem!

During a Wimbledon match being watched live online by 100,000 internet viewers, Maria Sharapova loses a contact lens. Afraid it might get stepped on, she refuses to let anyone help her look for it. On her hands and knees, Maria can examine 52 sq ft of grass per minute. The tournament webmaster notices that for every 3 minutes that Maria’s search continues, the number of viewers doubles. If Maria has to search her entire side of the court without finding the lens, how many people will be watching by the end?
