Bailey is starving! It's lunchtime and she wants to order some food and an iced coffee from Starbucks to be delivered through GrubHub. Bailey lives in a city where the total sales tax is 9%. If the cost of her food and coffee is $21.25, how much tax will Bailey owe on her ordeer?(2 points)

To calculate the sales tax, you can use the formula:

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

Bailey's cost is $21.25 and the tax rate is 9% (or 0.09 as a decimal).

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

Now, perform the multiplication:

\[
\text{Sales Tax} = 21.25 \times 0.09 = 1.9125
\]

Rounding this to two decimal places, Bailey will owe approximately $1.91 in sales tax.

So, the correct response is:

**$1.91**
