Once again, there are many approaches to this problem - one is to guess at
what
the original price might have been, and then see whether your guess will
make the
sale price bigger or smaller than $25.09. Then adjust your guess.
Or you could work backwards from the sale price - but think
carefully
about how to get the original price back from the sale price!
As always, be sure to explain the
work you did to arrive
at your answers!
