To calculate the total cost of the pizza, including sales tax and tip, follow these steps:

  1. Calculate the sales tax:

    • Sales tax rate = 6.5%
    • Cost of the pizza = $23.00
    • Sales tax = \( 23 \times 0.065 = 1.495 \)
    • Rounded to the nearest hundredth: Sales tax = $1.50
  2. Calculate the price of the pizza including sales tax:

    • Price with sales tax = Cost of pizza + Sales tax
    • Price with sales tax = \( 23 + 1.50 = 24.50 \)
  3. Calculate the tip:

    • Tip rate = 15%
    • Tip = \( 24.50 \times 0.15 = 3.675 \)
    • Rounded to the nearest hundredth: Tip = $3.68
  4. Calculate the total cost:

    • Total cost = Price with sales tax + Tip
    • Total cost = \( 24.50 + 3.68 = 28.18 \)

Therefore, the total cost of the pizza including sales tax and tip is $28.18.
