Solve the problem.

A company adopts an advertising campaign to weekly add to its customer base. It assumes that as an average fifty percent of its new customers, those added the previous week, will bring in one friend, but those who have been customers longer will not be very effective as recruiters and can be discounted. A media campaign brings in $10,000$ customers initially. What is the expected total number of customers with whom the company can expect to have dealings?

The sum diverges to infinity.

$15,000$ customers

$20,000$ customers

$30,000$ customers
