Perm costs 60
95-5=90
x+2x=90
2x=30
x=60
30*2=60
60+30=90
95-5=90
x+2x=90
2x=30
x=60
30*2=60
60+30=90
The cost of the haircut + the perm is $95, and the Perm is double the price of the Haircut. $5 was spent on lunch so..
95 - 5 = 90 : Get rid of the money spent on lunch.
90 = x + 2x : x is Haircut, 2x is Perm.
90 = 3x : Divide both sides by 3.
x = 30
The haircut is $30, so the Perm is $60 - because Perm is double the price.
