To calculate the sales tax on Bailey's order, you can use the following formula:
Sales Tax = Cost of Item * 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).
Sales Tax = $21.25 * 0.09
Sales Tax = $1.9125
Now, we typically round sales tax to two decimal places:
Sales Tax ≈ $1.91
Therefore, the amount of tax Bailey will owe on her order is $1.91.
