Name it!!  Ask yourself, "What does the problem want?"  When you find the answer to that question, give it a name.  You'll be about half done.

Go!

It wants the.... Original price, x?

tkhunny · Answer

Well, there you go.

How much was the discount?  Not the RATE of the discount.  That's 30%.  What WAS the discount?

anonymous · Answer

Hmmm, if i knew the original amount i could tell ya xD

tkhunny · Answer

Nonresponsive.  Why do you think we just NAMED the original amount.  You DO know the Original Amount.  It's x.  We just decided that.

I ask again, what was the discount?

tkhunny · Answer

If the original price were $100, how would you calculate the discount?

anonymous · Answer

100 minus 30% of 100

tkhunny · Answer

Perfect.

Now rewrite that with one modification.  Everywhere you wrote "100", write "x", instead.
