Answer: The original number of CDs is between 1000 and 1500.
Step-by-step explanation:
Since we have given that
Number of copies of a popular CD left to be sold in the store = 15
According to question, this is between 15 and 1.5% of the original number of copies of the CD in the store.
Let the original number of copies of the CD in the store be 'x'.
Now, 15 is equal to 1% of the original number of copies of the CD, it becomes
![1\%\ of\ x=15\\\\\frac{1}{100}\times x=15\\\\x=15\times 100\\\\x=1500](https://tex.z-dn.net/?f=1%5C%25%5C%20of%5C%20x%3D15%5C%5C%5C%5C%5Cfrac%7B1%7D%7B100%7D%5Ctimes%20x%3D15%5C%5C%5C%5Cx%3D15%5Ctimes%20100%5C%5C%5C%5Cx%3D1500)
Or if 15 is equal to 1.5% of the original number of copies of the CD, it becomes
![1.5\%\ of\ x=15\\\\\frac{1.5}{100}\times x=15\\\\\frac{15}{1000}x=15\\\\x=\frac{15\times 1000}{15}\\\\x=1000](https://tex.z-dn.net/?f=1.5%5C%25%5C%20of%5C%20x%3D15%5C%5C%5C%5C%5Cfrac%7B1.5%7D%7B100%7D%5Ctimes%20x%3D15%5C%5C%5C%5C%5Cfrac%7B15%7D%7B1000%7Dx%3D15%5C%5C%5C%5Cx%3D%5Cfrac%7B15%5Ctimes%201000%7D%7B15%7D%5C%5C%5C%5Cx%3D1000)
Hence, the original number of CDs is between 1000 and 1500.
