Hi there!

Let th' number of CD's be = X

• Setup fee = $ 5,500
• Per CD's charge = $ 1.00
• Desired cost per CD = $ 3.50

Acc'rding to the question :-

Desired cost per CD = Setup fee + Cost per CD

⇒ (3.50 × X) = $ 5, 500 + ($ 1.00 × X)

⇒3.50 X = $ 5, 500 + 1.00 X

Combine like terms :-

⇒ 3.50 X - $ 1.00 X = $ 5, 500

⇒ 2.50 X = $ 5, 500

⇒X = = 2, 200 CD's

Hence,
The required answer is = X = 2, 200 CD's

~ Hope it helps!
