A marketing manager is planning a series of events to promote a new product line. She is considering various event types, including webinars, conferences, and trade shows. Each event type has distinct characteristics and potential impacts on audience engagement and lead generation. If she allocates a budget of $10,000 for these events, and she estimates that a webinar can generate leads at a cost of $50 per lead, a conference at $100 per lead, and a trade show at $200 per lead, how many leads can she expect to generate if she decides to host only webinars with the entire budget?
