how to calculate break even in number of guest nights for the 2 marketing options (see options). I need some guidance on how to start the problems,

Option 1: Local Partnerships Their rst strategy was to create relationships with businesses that actively promoted Rwanda's backpacking culture. These included hotels, campsites, youth hostels. and budget tourism companies operating in Rwanda as well as in popular backpacking cities such as Kampala, Nairobi, and Dar es Salaam. Their plan was to distribute brochures and posters at these locations in exchange for advertising space at the Lake Muhazi campsite. The partners hoped that these relationships would help create word-of- mouth discussion and lead to greater sales; although they were not sure how many businesses would cooperate with them. The cost of distributing these materials would be $50 per month and was expected to generate one or two additional guests per night. The partners were also considering offering commission fees to any participating businesses based on how many customers theyr sent to the Lake Muhazi campsite. Such businesses would be paid 5 to 10 per cent of revenue for every hooking they completed The partners expected this would generate more sales than their brochure strategy and would lead to higher participation rates among local businesses. The cost of this program would be $100 per month and was expected to result in two to four additional guests per night
