Answer 1

Hi there! The answer is 7%

The price of the book is $ 22.
Santino bought it for $ 23.54.
Therefore, the amount of tax is $ 1.54

Now we can find the sales tax rate by using the following formula:
$tax \: rate = \frac{tax}{price \: excluding \: tax} \times 100\%$

Filling in gives:
$tax \: rate \: = \frac{1.54}{22} \times 100\% = 7\%$
