The wording of the problem is careless enough that there are different possible interpretations.
One interpretation of a "10% sale" is a going-out-of-business liquidation sale where everything is being sold at 10% OF its regular price. In that case the regular price is 10 times the sale price, which is 10*$18=$180.
However, presumably the problem is supposed to be about a sale in which the sales prices are 10% OFF OF the regular price (a "10% off sale", not a "10% sale").
In that case, with 10% off the price is 90% OF the regular price. Since the sale price is $18,
ANSWER: The regular price is $20.
