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".
