1 haircut = 47 dollars
1 colouring = 98 dollars
Step-by-step explanation:
Let be equal to the cost of 1 haircut.
Let be equal to the cost of 1 colouring treatment.
<u>1) Form equations</u>
Equation 1: 3 haircuts + 1 colour = 239 dollars
⇒
Equation 2: 2 haircuts + 1 colour = 192 dollars
⇒
<u>2) Solve the system of equations</u>
Subtract equation 2 from equation 1 to cancel out y (elimination)
-
⇒
Therefore, Natalie charges 47 dollars for 1 haircut.
Plug x back into one of the equations to solve for y
Subtract both sides by 94
Therefore, Natalie charges 98 dollars for 1 colouring treatment.
