[Dan]

Hi..I have this math question that is really confusing and I can't get it at all..if someone can help me with it that would be awsome!..it is sort of long..but try your best..Thanks!

Suppose we make writable disks. In an hour, we can make 52 CD-R's and 30 CD-RW's. Also in that hour, we can mkae 16 DVD-R's and 21 RW's. Create a matrix for the data where the first row represents CD's made, the second row represents DVD's. The first column should be in -R's and the second column is RW's.
