Answer 1

To calculate the restaurant bill with sales tax and an added tip, follow these steps:

1. Calculate Sales Tax:

   • The sales tax rate is 5.75%.
   • The original bill is $19.34.
   • Sales Tax = Original Bill × Sales Tax Rate
   • Sales Tax = $19.34 × 0.0575 = $1.11 (rounded to the nearest hundredth)

2. Calculate Total Bill Before Tip:

   • Total Bill Before Tip = Original Bill + Sales Tax
   • Total Bill Before Tip = $19.34 + $1.11 = $20.45

3. Calculate Tip:

   • The tip rate is 18%.
   • Tip = Total Bill Before Tip × Tip Rate
   • Tip = $20.45 × 0.18 = $3.68 (rounded to the nearest hundredth)

4. Calculate Total Bill After Tip:

   • Total Bill After Tip = Total Bill Before Tip + Tip
   • Total Bill After Tip = $20.45 + $3.68 = $24.13

In summary:

• Before tip: $20.45
• After tip: $24.13

The correct response is:

• Before tip: $20.45 After tip: $24.13
