Well I don't know !
Let's get together and work it out.

We don't know the original price yet, but we need to give it a name so that we can work with it in math equations and stuff. I'm going to call it OP.

OP was reduced by 45% before Fred came along.
That means that 45% of OP was cut off and discarded.
How much of it was left ?
Well, before it was reduced, 100% of it was marked on the price tag.
After 45% was cut off, there was (100% - 45%) = 55% of it left.

That's what Fred paid for the one he bought . . . 55% of OP.

55% of OP is $124 .

We have to change that sentence into math.

-- 55% means 0.55
-- "of" means "times"
-- "is" means 'equals sign'

So now we can write: 0.55 x OP = $124

There's the equation.
Now, divide each side
by 0.55, and you get OP = $124 / 0.55

= $225.45
