A music store had a going out of business sale. During the first week of the sale, all items were marked 20% off. During the second week of the sale, all items were marked down an additional 30% off the already reduced price. Monique came into the store during the second week and found that the flute she wanted had an original price of $1200. How much did the new flute cost, in dollars, after being marked down and before sales tax was added?

1200-240=960

That's the discount price after you apply the 20% off discount

Now we must take off 30%
