The original price is $240.00

Let the original price be #x# so all of it is: #100%x#

But % is a unit of measurement worth #1/100# giving #100/100 x#

The current price is #100/100x-15/100x = 85/100x#

We are told that this is $204 giving

#85/100x=$204#

Multiply both sides by #100/85# giving:

#x=$204xx100/85#

#x=$240#
