Christopher bought a new watch at the store when they were having a 20% off sale.

If the regular price of the watch was $48, what did Chris have to pay after the discount was applied?

Let w represent the cost of the watch.  Then the discounted price would be (1.00-0.20)($48) = 0.8($48) = $38.40   (answer)

Not sure what the question is?
