Bailey is starving it's lunch time 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 would Bailey owe on her order a $2.13 $8.99 see $1 d $1.91

To calculate the sales tax on Bailey's order, you can use the following formula:

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

In this case:

- Cost = $21.25
- Sales Tax Rate = 9% = 0.09

Now, plug in the numbers:

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

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

Rounding this to the nearest cent, Bailey would owe approximately $1.91 in sales tax.

So the correct answer is **d) $1.91**.
