Hi mmann,

I don't think that the question makes sense.

It says in the question that Nakisa bought 22CDs

22*$16 = $352 which is more than Nakisa spent.

See, it does not make sense.

I think this might mean
n CD + n DVD = 22
16n CD + c DVDn DVD = 328

where n is number and c is cost. However, we still need to know the cost of a DVD to answer the qustion.
