A furniture store pays a certain amount for a mattress, called the wholesale price. Then, the store marks up the amount they paid to 225% of their cost (wholesale price) to sell it (retail price).

The mattresses didn't sell, so later they put the mattress on sale for 50% off of the retail price. A customer just bought the mattress on sale and paid $800.

What was the retail price (selling price) of the mattress, before the discount? #
