Shared Bill Calculation

A group of friends dines together and decides to split the bill. Each friend orders one or more items with known costs. If the total bill exceeds \(100\), they receive a 10% discount on the entire bill. The discount is applied proportionally according to each person’s individual order. Calculate the amount each friend must pay, rounding the result to two decimal places.
