To find the total cost of the meal, plus tax and tip, we need to follow these steps:
Find the amount of tax that was added to the bill:
tax = 0.06 * 18.35 = 1.10
Add the tax to the bill to find the subtotal:
subtotal = 18.35 + 1.10 = 19.45
Find the tip on the subtotal:
tip = 0.20 * 19.45 = 3.89
Add the subtotal and tip to get the total cost:
total cost = 19.45 + 3.89 = 23.34
Therefore, the total cost of the meal, plus tax and tip, is $23.34.
