Answer:
20 CDs
Step-by-step explanation:
Assuming you can't buy 1 CD, you have to buy 2 CD's for 15.95, let's see how many 2CD-Batches we can buy with 60:
60/15.95 = 3.76 CD batches
We can't buy the fractional amount, so we have to buy "3" 2-CD-Batches.
Thus, we will have 3 * 2 = 6 CD's now
Since we had 14 and now we buy 6, we will have
14 + 6 = 20 CDs now.
20 CDs
