Can you please help with questions in the picture?

For questions 18 - 21 use the following information. "Website Design Associates" (WDA) provides website design services for small business. They have three types of potential customers: - Type 1: Small businesses without a need for secure online transactions - Type 2: Small businesses with a need for secure online transactions, but no need for storage of customers' personal information Type 3: Small businesses with a need for both secure online transactions and storage of customers' personal information WDA's services come in three distinct versions: - "Basic" : web design without secure online transactions - "Intermediate" : web design with secure online transactions but no customer data storage - "Extreme" : web design with secure online transactions and customer data storage All costs for Website Design Associates are relatively small and can be assumed to be zero. The marginal willingness to pay for the different customer types is given in the following table: Basic Upgrade to Upgrade to Intermediate Group Sizes Extreme Type 3 1,000 500 200 10 Type 2 700 400 100 20 Type 1 600 100 50 25 21. Suppose that due to changes in privacy laws that make the storage of consumers' personal data more problematic, Website Design Associates can no longer offer its "Extreme" product. Thus, the table of the previous 3 questions becomes: Upgrade to Basic Intermediate Group Sizes Type 3 1,000 500 10 Type 2 700 100 20 Type 1 600 100 25 What is the revenue-maximizing menu in this case? What are the seller's revenue and the total consumer surplus generated by the revenue-maximizing menu
