Arif and keisha go to a restaurant fot dinner. their meals total $13.75 and the tax is 5%
question: arif and keisha want to leave a 15% tip based on the bill and tax combined. how much should they leave? explain.

The total cost of the dinner meals taken by Arif and Keisha = $13.75
Percentage of tax that need to be given = 5%
Then
Amount of tax that needs to be given = (5/100) * 13.75 dollars
                                                           = 13.75/20 dollars
                                                           = 0.687 dollars
                                                           = 0.69 dollars
So
The total amount that needs to be
paid for dinner including tax = (13.75 + 0.69) dollars
                                             = 14.44 dollars
Percentage of tips that they both want to leave = 15%
Then
Amount of tips that need to be given = (15/100) * 14.44
                                                           = 216.6/100 dollars
                                                           = 2.17 dollars
So
The total amount that they should leave = (14.44 + 2.17) dollars
                                                                 = 16.61 dollars
So they should leave a total of $16.61 in the restaurant.
