Jocelyn angelica bought a dress marked "sale price is 18% off." the cashier told her she saved $23. how much was the price of the dress, before markdown?

Represent the dress price using d.
                                                                                                             $23
Savings were 0.18d = $23.  Dividing both sides by 0.18, we get d =
                                                                                                             0.18

= $127.78.

Check:  What is 18% of $127.78?  0.18($127.78) = $23.

Thus, the original price was $127.78, the savings $23, and the price paid $104.78.
