Understand Problem Context: Understand the context of the problem. Camilla borrows a book from the library and is charged a late fee of $0.10 per day after the book is due. The book is due after 21 days, and the expression for calculating the late fee is 0.10(d-21).Analyze Expression: Analyze the expression 0.10(d-21). The expression 0.10(d-21) is used to calculate the total late fee. The 0.10 represents the late fee per day, and (d-21) represents the number of days the book is late.Determine Representation: Determine what (d-21) represents. Since d represents the total number of days Camilla has the book and 21 is the number of days she can have it without a late fee, (d-21) represents the number of days the book is late.
