Step 1 ：Given values are total purchase price = $28.08 and sales tax rate = 8%.

Step 2 ：First, calculate the selling price using the formula: selling price = total purchase price / (1 + sales tax rate).

Step 3 ：Substitute the given values into the formula: selling price = $28.08 / (1 + 0.08) = $26.00 (approximately).

Step 4 ：Next, calculate the sales tax using the formula: sales tax = total purchase price - selling price.

Step 5 ：Substitute the values into the formula: sales tax = $28.08 - $26.00 = $2.08 (approximately).

Step 6 ：Final Answer: The selling price of the book is approximately \(\boxed{26.00}\) and the sales tax is approximately \(\boxed{2.08}\).
