Could you please help me with this?
Music Spending. Sean has $37 to spend. He can spend all of it on two compact discs and a casette, or he can buy one CD and two cassettes and have $5.00 left over. What is the price of a CD? of a casette?

Since he has no money left after buying two CDs, then each CD is $18.50.
If he buys one CD (for $18.50) and one cassette, and has $5 left over, he must have spent ___ on the cassette.
You don't need algenra to to this.
