Question

Write an expression for the total cost of a book with ten percent tax included. Let p = price of the book before tax.

Answer 1

The expression for the total cost of a book with ten percent tax included is Total Cost = p + 0.1p.

Step-by-step explanation:

The expression for the total cost of a book with ten percent tax included can be represented as:

Total Cost = p + 0.1p

Here, p represents the price of the book before tax. To find the total cost, we add the price of the book before tax (p) to 10% of the price (0.1p). This accounts for the 10% tax on the book.
