Media outlets such as ESPN and FOX Sports often have websites that provide in-depth coverage of news and events. Portions of these websites are restricted to members who pay a monthly subscription to gain access to exclusive news and commentary. These websites typically offer a free trial period to introduce viewers to the websites. Assume that during a recent fiscal year, ESPN.com spent $4,200,000 on a promotional campaign for the ESPN.com websites that offered two free months of service for new subscribers. In addition, assume the following information: Number of months an average new customer stays with the service (including the two free months) Revenue per month per customer subscription Variable cost per month per customer subscription 14 months $10.00 $5.00 Determine the number of new customer accounts needed to break even on the cost of the promotional campaign.
