The amount of bill before tax = $193.75
Percentage of tax added by the waiter = 4%
Amount of tax added by the waiter = (4/100) * 193.75 dollars
= 775/100 dollars
= 7.75 dollars
Total bill after tax = (193.75 + 7.75) dollars
= 201.50 dollars
Percentage of tips that Luca wants to give = 16%
Amount of tips that Luca wants to give = (16/100) * 201.50 dollars
= 32,24 dollars
The total amount that Luca needs to pay = (201.50 + 32.24) dollars
= 233.74 dollars
