Arestaurant bill is $21. you leave a 15% tip. how much do you pay including the tip?

Total payment done is $24.15

Step-by-step explanation:

Given in the question restaurant bill is $21 and tip left was 15% of the bill.

Then we have to find the total amount paid.

Since bill is = $21

Therefore as per question tip given = $21×15%

                                                           = (21×15)/100 = 315/100 = $3.15

Now total payment done = Restaurant bill + tip paid

                                         = 21 + 3.15 = $24.15

Answer is $24.15 total payment done.
