Hi!

Algebraic expression. First thing to do is write some variables.

Set o = the original price of an item, and n to the new cost of the item.

Since the item is 25% off, you subtract 25% of itself from it's original cost, to get the new cost. That's written out as:

n = o - 1/4o

Now to fully simplify this. o, is technically 1 * o. So what is 1/4 subtracted from 1? 3/4. The equation therefore becomes:

n = 3/4o

Hope this helped!
