A sales representative is analyzing the effectiveness of various lead sources for their company, which operates in the technology sector. They have tracked leads from three different sources over the past quarter: social media, email campaigns, and referrals. The company generated a total of 300 leads, with 120 from social media, 90 from email campaigns, and 90 from referrals. The sales representative wants to determine the conversion rate for each lead source, defined as the number of leads that resulted in a sale divided by the total number of leads from that source. If the conversion rates are as follows: social media leads converted at 25%, email campaign leads at 30%, and referral leads at 50%, what is the total number of sales generated from these leads?
