Section 2: Sales Tax

To calculate the sales tax that Bailey will owe, you can use the following formula:

\[ \text{Sales Tax} = \text{Cost} \times \text{Sales Tax Rate} \]

In this case, the cost of the food and coffee is $21.25, and the sales tax rate is 9% (or 0.09 in decimal form).

Now, plug in the values:

\[ \text{Sales Tax} = 21.25 \times 0.09 \]

Calculating that:

\[ \text{Sales Tax} = 1.9125 \]

Since sales tax is typically rounded to two decimal places, it will be approximately $1.91.

So, the correct response is **$1.91**.
