You can immediately subtract the $5 for lunch, to find that the haircut and perm will cost a total of $90. You know that the perm costs twice as much as the haircut.

Let x = cost of haircut
Let 2x = cost of perm

x + 2x = 90
3x = 90
x = 30

Perm: 2x = 60

So the haircut is $30, the perm is $60, and the lunch is $5.

The haircut must cost
