Answer 1

To find the total cost for Bailey, including tax, we need to add the sales tax to the original cost of her food and coffee.

1. **Calculate the tax**:
- Cost of food and coffee: $21.25
- Sales tax rate: 9%

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

Rounding this to the nearest cent gives us $1.91, which matches the answer you noted.

2. **Calculate the total cost**:
- Total cost = Cost + Tax
\[
\text{Total Cost} = 21.25 + 1.91 = 23.16
\]

So, the total cost of Starbucks for Bailey, including tax, is **$23.16**.

The correct response is:
- **$23.16**
