Answer 1

To find Paul's total cost for the lunch, including tip and tax, we need to follow these steps:

1. Calculate the tip:
   Tip = 15% of $14.56
   Tip = 0.15 * 14.56 = $2.184

2. Calculate the sales tax:
   Sales Tax = 7% of $14.56
   Sales Tax = 0.07 * 14.56 = $1.0192

3. Calculate the total cost:
   Total Cost = Cost of lunch + Tip + Sales Tax
   Total Cost = 14.56 + 2.184 + 1.0192

Now, let's do the calculation:

Total Cost = 14.56 + 2.184 + 1.0192
Total Cost = 17.7632

Now, we round to the nearest hundredth:

Total Cost ≈ 17.76

So, the answer is:

17.76
