Luca is planning to pay the restaurant bill for his coworkers. The bill was $193.75. A 4% tax was then added by the waiter. If Luca wants to leave a 16% tip on the total amount including the tax, how much should Luca pay?

A) $201.50

b) $217.50

c) $224.75

d) $233.74

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

The correct option among all the options that are given in the question is option "d".
