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.
