I need help finding out how to find the lower and upper bound and make sure I'm doing right! I will submit a picture of what I've done so far

Internet Case Study: Biales Waste Disposal, GmbH Biales Waste Disposal, GmbH, headquartered in the industrial city of Dusseldorf, Germany, operates seven specially-constructed semi-trailers and cabs for commercial long-distance hauling of radioactive waste materials. Each truck averages one completed load per week, picking up the radioactive containers from chemical companies and other manufacturers in central Europe. The loads are carefully driven to a government site near Dresden, which until the reunification was a manufacturing center in East Germany. Currently, pickups are made in eight countries: Italy, Germany, Austria, France, Belgium, Netherlands, Denmark, and Poland. Biales maintains an office in each country's capitol. Staffing includes not only a manager and a secretary at each national office, but a part-time lobbyist/attorney to assist in the many political, cross-cultural, border, and legal issues that arise in the nuclear waste disposal industry. Sybil Biales, owner of the firm, is seriously considering dropping Italy as source of business. Last year, only 25 truckloads of wastes were handled there. Since textile manufacturers in northern Italy are the primary source of trucking for Biales, the size and revenues from their shipments will determine if it is profitable to retain an office and do business in that country. To analyze the Italian market, Biales gathers data on last year's shipments and revenues, as shown below. Each of the 25 trucks that were loaded in Italy last year carried between 28 and 48 barrels of waste. The income generated per barrel differed significantly (ranging from 50 to 80 Euro) based on the type of radioactive material being loaded and the weight of the barrels to be shipped. Barrels Probability Revenue Probability 28 0.12 E 50 0.20 33 0.16 E 60 0.44 38 0.24 E 70 0.28 43 0.36 E 80 0.08 48 0.12 Biales decided that if she were to simulate 25 truckloads out of Italy she could determine if it would be profitable to continue to operate there next year. She estimates that each shipment to the Dresden dump site costs E 900, including driver, gasoline, and truck expenses; other cargo and loading and unloading costs average E 120 per shipment. In addition, it costs E 41,000 per year to operate the Italian office, including salaries and indirect overhead costs from the home office in Dusseldorf. Will the shipments in Italy next year generate enough revenues to cover Bigles' costs there? Run the simulation for total profit 200 times and determine the average profit to answer the question.Number of Barrels Loaded Lower Bound Upper Bound No. of Barrels 0 0.12 0.12 0.28 0.28 0.52 0.52 0.88 0.88 Revenue per barrel Lower Bound Upper Bound Revenue 0 0.2 0.2 0.64 0.64 0.92 0.92barrels Probbaility F9x) 28 0.12 0.12 33 0.16 0.28 38 0.24 0.52 43 0.36 0.88 48 0.12 1 Revenue Probability F(X) 50 0.2 0.2 60 0.44 0.64 70 0.28 0.92 80 0.08
