A sales representative is analyzing the effectiveness of various lead sources for their product line. They have tracked leads from three different sources over the past quarter: social media, email campaigns, and trade shows. The representative found that social media generated 150 leads, email campaigns generated 100 leads, and trade shows generated 50 leads. To evaluate the conversion rates, they discovered that 20% of social media leads converted to sales, 30% of email campaign leads converted, and 10% of trade show leads converted. If the representative wants to calculate the total number of sales generated from these leads, what is the total conversion from all sources?
