This challenge is an advanced version of last month’s Challenge Oct-2025, when a freelance developer needs to design a website with as many features as possible, but also maximizing the total value of the selected features. Now you have several additional requirements:

• Features 3 and 4 can be chosen only together.
• Feature 2 cannot be combined with Feature 3.
• Only one of the features 8, 9, and 10 can be selected. Otherwise, the cost of each of these features will be increased by 10%.
• If 5 or more features are selected, 5% discount is provided.

You want to offer a design that maximizes the total value while minimizing the total cost. Link
