Respuesta :

The price of the service before the tip will be equal to $35.

What is the percentage?

The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.

Given that:-

  • Talia gave her hairdresser a 20 per cent tip, which amounted to $7

The total price of the service will be calculated as:-

20%   =   $7

10%   =    7/2

100%  =   10 x 7/2

100%    =   $35

Therefore the price of the service before the tip will be equal to $35.
