Answer 1

Greetings!

Answer:

$30

Explanation:

Lets use x as the price for the haircut.

If the perm is 2 * the amount of the haircut, this can be shown by 2x (2 times the value of x which is the haircut price).

We know the price for lunch so we simply need to subtract this value from 50:

50 - 5 = 45

So 45 is the total price for the perm and haircut.

Now we can add 2x (price of perm) and x (price of haircut):

2x + x = 3x

So 3x = 45

Divide both sides by three to get x:

x = 15

So if the perm is 2x the cost of the haircut, and the haircut costs 1x which is 15, then we can multiply thise value by 2:

15 * 2 = 30

So the perm cost $30!

Hope this helps!
