Answer 1

To calculate how much tax Bailey will owe on her order, we will use the total cost of the food and coffee, which is $21.25, and multiply it by the total sales tax rate of 9%.

1. Calculating the Tax: \[ \text{Tax} = \text{Cost} \times \text{Tax Rate} = 21.25 \times 0.09 = 1.9125 \] Rounding to two decimal places, the tax is $1.91.

So, the answer to the first question is: $1.91.

2. Calculating the Total Cost Including Tax: To find the total cost including tax, we add the tax amount to the original order amount. \[ \text{Total Cost} = \text{Cost} + \text{Tax} = 21.25 + 1.91 = 23.16 \]

So, the total cost including tax is $23.16.

The answer to the second question is: $23.16.

3. Calculating the Overall Cost Including Delivery Fee and Tip: Now we will add the delivery fee and tip to the total cost including tax. \[ \text{Total Spending} = \text{Total Cost} + \text{Delivery Fee} + \text{Tip} = 23.16 + 3.50 + 4.00 = 30.66 \]

Therefore, Bailey's total spending on her lunch is $30.66.

The answer to the third question is: $30.66.
