The price of Ravi's lunch, before tax and tip was added to the total cost of the meal is $13.19.
<h3>What is the price of the lunch?</h3>
Both the tax and the tip paid would increase the cost of the meal. Thus, their dollar value has to be subtracted from the total amount he pays.
Value of the lunch after the tip has been removed = (1 - 0.2) x 17.92 = $14.34
Value of the lunch after the tax has been removed = (1 - 0.08) x $14.34 = $13.19
