What is a percentage?
A percentage is a number or ratio that can be expressed as a fraction of 100. Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
For the given situation,
Restaurant bill = $24.00
Tax percentage = 6% = 0.06
Tip percentage = 20%
6% tax is added to the bill,
Total price = [tex]24+24(0.06)[/tex]
⇒ [tex]24+1.44[/tex]
⇒ [tex]25.44[/tex]
20% tip on the total including the tax,
⇒ [tex]25.44+25.44(0.20)[/tex]
⇒ [tex]25.44+5.088[/tex]
⇒ [tex]30.528[/tex] ≈ [tex]30.53[/tex]
Hence we can conclude that the total price she should pay including tax and tip percentage is option (C) $30.53 is the correct answer.
