Final answer:

To calculate the total bill with tax and tip, calculate the sales tax by multiplying the meal cost by the tax rate, add that to the original cost, calculate the tip based on the total cost including tax, and add the tip to get the total amount to be paid.

Step-by-step explanation:

The student asked how to find the total bill after including tax and tip. To solve this problem, we can follow these steps:

  1. Calculate the sales tax by converting the percentage to a decimal and then multiplying by the cost of the meal.
  2. Add the sales tax to the original meal cost to get the total cost including tax.
  3. Calculate the tip amount by converting the tip percentage to a decimal and multiplying it by the total cost including tax.
  4. Add the tip to the total cost including tax to find the total amount paid.

Let's use the details from a similar example provided. If Jerod's total food cost is $47.50 and the restaurant charges 6% sales tax:

  • The sales tax would be 0.06 × $47.50 = $2.85.
  • The total cost including tax would then be $47.50 + $2.85 = $50.35.

Now, we add a 20% tip:

  • The tip would be 0.20 × $50.35 = $10.07.
  • The total amount paid including tip would be $50.35 + $10.07 = $60.42.

Therefore, Jerod and his friends will pay $60.42 at the restaurant's register using a credit card, including the sales tax and tip.
