Let's create an expression with the given variables and values to better understand the problem.

y=100-(45+11c)

This equation subtracts the value of the cd player and the CDs from the money on the gift card. 

We can simplify the equation a little more to make it easier to solve.
y=55-11c

Now, we can see how many CDs we can buy with the remaining money on the gift card by solving for 'c'.
11c=55
c=5

We can buy 5 CDs with the money remaining on the gift card.
