I'll help you understand math!

Alllllllright, Kelani. Let's see what we can do.

Let's let the number of disks = d.

We have that you need to spend 2125 plus 4.25d, right?

If you sell each disk for $10.50, then your sales would equal 10.50d, right?

We need to find when your cost equals your sales, so 2125 + 4.25d = 10.5d.

Can you solve it from here?

I thinks so.

I came up with 340 copies.
