calculate step by step

Ms. Jenny Joy is planning to open her first own business project: a little caf close to the university district of the imaginary town of Brightside. She has rented a small, but nice venue for the caf. She has worked hard to keep the target opening date of 1 June. There is a very important report missing from her paperwork though; she does not know how much profit she can expect during the first 3 months of operation. She remembers from university finance class that the best way to prepare a profit plan is to consider different scenarios. She has gathered all the relevant information for the profit analysis and for the sake of simplicity estimated two possible outcomes: "good" and "almost good. Information about costs and revenues: Average revenue from drinks and food: 22 per person Cost of drinks and food: 14 per person Rent fee: 1000 per month Utilities: 1200 per quarter She does not plan to hire employees in the first three months. Renting the coffee machine: 6000 per year Other costs: 3000 in the first month and 5% less in every upcoming month Probability of Number of guests PER scenario DAY (assume 20 working days per month) Good scenario 55% 40 Almost good scenario 45% 30 Required: 6.1) Prepare a monthly analysis of Ms Joy's profits based on her revenues and costs for the three months under both scenarios.
