Answer: At x= 25 there is a break even point .
Step-by-step explanation:
Let the number of CDs be x
For the case of iTunes,
Cost of each CD = $12
For the case of Best Buy,
Number of CDs of free of cost = 5
Number of CDs more than 5 = $15
We need to find the "Break even point ":
According to question,
[tex]12x=15(x-5)\\\\12x=15x-75\\\\12x-15x=-75\\\\-3x=-75\\\\3x=75\\\\x=\frac{75}{3}\\\\x=\$25[/tex]
Hence, At x= 25 there is a break even point .
