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
I think its 8 because 64 divided by 8 is 8.
To solve the expression 7x + y we can substitute x with 2 and y with 6.
= 7(2) + 6
= 14 + 6
= 20
Best of Luck!
