$22*.07(move the decimal two spaces left)
=1.54

$22+$1.54= $23.54

Answer 2

Answer:  The answer is (C) 7%.

Step-by-step explanation:  Given that Santino bought a book for $23.54 and the original price of the book was $22. We are to find the sales-tax rate of the book.

The sales tax on the book will be

$S=\ 23.54-\ 22=\ 1.54.$

Therefore, the sales tax rate will be

$r=\dfrac{1.54}{22}\times 100\%=\dfrac{154}{22}\%=7\%.$

Thus, the correct option is (C).
