Answer 1

Let P=Perm cost

Let H = Haircut cost

Let L = Lunch cost

 

Perm costs twice as much as haircut so..  P = 2H

L = 5

 

H + P + L = 68    the total cost is $68

 

H + 2H + 5 = 68   since P = 2H and L=5

 

3H + 5 = 68

 

3H =63

 

H = 63/3

 

H = 21 

 

A Haircut is $21

Perm = 2H = 2(21) = $42
