Please help me solve the following problem as the picture shown or give me some suggestion. Thanks.

[In many areas of the US, Xnity (Comcast's cable intemet service) is a monopolist for fast internet service and it is for these markets that you are asked to reevaluate the product offerings and pricing strategy. After extensive market research, it has determined that its customers fall into three categories: Gamers, Streamers and Casual users. Gamers are willing to pay more for their intemet service than are Streamers and Casual users. The willingness to pay for a month's service with connections of different speeds for a typical Streamer, Gamer and Casual user is shown in the table below: Xnity can offer any speed up to llOMbps at a marginal cost of zero. You have reliably estimated that there are 2 million Gamers, 4 million Streamers and 6 million Casual users in the service area. a. Currently, the provider offers two tiers of service: 65Mbps for $25 per month, and 1 10Mbps for $50 per month. How much prot is Comcast making on these offerings? b. Can you improve on Comcast's pricing strategy, given these two tiers of service offerings? 0. Given these consumer preferences, what combination of tiers offered and prices earns the provider the most prot? Explain. (1. Good news! Further research reveals that Gamers don't view other internet service providers as good alternatives even for slower speeds, due to the better reliability of Xnity; your research reveals that Gamers are actually willing to pay $60 for the 30Mbps service, rather than the earlier estimate of $35. How would you revise Comcast's pricing strategy in light of this new information
