To calculate the sales tax Bailey will owe on her order, you can use the following formula:
Sales Tax = Cost of Order × Sales Tax Rate
In this case, the cost of the order is $21.25 and the sales tax rate is 9% (or 0.09).
Calculating the sales tax:
Sales Tax = $21.25 × 0.09 = $1.9125
Rounding to the nearest cent, the sales tax will be approximately $1.91.
So, the correct response is $1.91.
