Celeste wants to have her hair cut and permed and also go to lunch. She knows she will need $95. The perm cost twice as much as her haircuts and she's $5 for lunch. How much does the perm cost?

Respuesta :

Cut= x
Perm= 2x
Lunch= $5
Total= $95

x+2x+$5=$95
         -$5   -$5

x+2x=$90

   3x=$90
------  ------
    3      3

x=$30

Cut= $30    Perm= 2($30) = $60

Perm= $60
