kherson [118]

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,

$12x=15(x-5)\\\\12x=15x-75\\\\12x-15x=-75\\\\-3x=-75\\\\3x=75\\\\x=\frac{75}{3}\\\\x=\$25$

Hence, At x= 25 there is a break even point .
