Verified Answer :

The orginal price was $22.5. You just multiply $7.50 by 3.

The answer is is $22.50

This problem can be solved with proportions/ratios and cross multiplication

To set it up, you can write out the ratios like this
@@MATH_TOKEN_0@@
where x=original price

or you can first write it like this, following the wording of the sentence
@@MATH_TOKEN_1@@
and then divide to get 
@@MATH_TOKEN_2@@

Now cross multiply (multiply numbers diagonal from each other together)
($
7.50)(3)=(1)(x)
$22.50=x

The answer is is $
22.50
