The genuine music discs produced by an audio-visual company sell for 50 yuan each, making a profit of 15 yuan. However, it is found that pirated products sell for only 20 yuan each. 
Due to the different cover packaging, many consumers can easily identify genuine and pirated CDs.
 if 100,000 pirated discs are sold, it will cause a loss of 1.5 million yuan to the audio-visual company.
