## Algebra 1

By dividing the number of cds by cost, you can how many cds you are getting per dollar, and which ever has more cds per dollar is the better deal. $30\div9.50=3.16$ In the 30 pack, you are getting 3.16 cds per dollar. or $50\div13=3.85$ In the 50 pack, you are getting 3.85 cds per dollar. Therefore, the 50 pack is a better deal because you are getting .69 more cds per dollar.
