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
