Well, first we calculate the discounted price that they were selling for in February. Half, or 50%, of $20 = $10, so in February the CDs were selling for $10. Then in March, an additional 10% percent discount was taken off. Now 10% of $10 = $1, so the final price would then be $20 - $10 - $1.
thank you
