A discount store takes 50% off of the retail price of a desk. For the store's holiday sale, it takes an additional 20% off of all furniture. The desk's retail price was $320. How much is the desk on sale for during the holiday sale?
Final price would be (.5)(.8)(320) or
50% of $320 = $160
0.8 * 160 = $128
We start at $320
50% is half, so the desk is reduced by half. That one's easy.
20% is 20/100 = 1/5, so you need to find 1/5 of the reduced price of the desk you worked out above, and subtract that from the reduced price.
Is that enough?
