To calculate Paul’s total cost for the lunch including tip and tax, you can follow these steps:

1. **Calculate the Sales Tax:**
\[
\text{Sales Tax} = \text{Cost of Lunch} \times \text{Sales Tax Rate} = 14.56 \times 0.07 = 1.0192
\]

2. **Calculate the Tip:**
\[
\text{Tip} = \text{Cost of Lunch} \times \text{Tip Rate} = 14.56 \times 0.15 = 2.184
\]

3. **Calculate the Total Cost:**
\[
\text{Total Cost} = \text{Cost of Lunch} + \text{Sales Tax} + \text{Tip} = 14.56 + 1.0192 + 2.184
\]
\[
= 17.7632
\]

4. **Round to the Nearest Hundredth:**
\[
\text{Total Cost Rounded} = 17.76
\]

Therefore, Paul’s total cost for the lunch, including tip and tax, is **$17.76**.
