The pack of 50 is the better deal

Work Step by Step

We must put both in the same units: dollars per CD. In order to do this, we divide the price of each CD by the number of CDs we get. Thus, we find: $9.50 \div 30 =.3167$ dollars per CD $13 \div 50 =.26$ dollars per CD .26 dollars per CD is less than .3167 dollars per CD, so the pack of 50 is the better deal.
