Answer:

Up to 8

Explanation:

Sarah has store credit of $153. New CDs cost $18. If we divide the credit by the cost per CD, we can find out how many she can buy:

#153/18=8.5#

Since we can't buy a partial CD, the maximum number of new CDs she can buy is 8 (and so she can buy 0, 1, 2, 3, 4, 5, 6, 7, or 8 new ones).
