To use the distributive property, we "distribute" a value on the outside of a set of parentheses to all of the values on the inside of the parentheses. For example...

6(3 + 9) = 6*3 + 6*9

For your problem, you only have one value 13.99, but we can split it apart to make it a little easier to work with (like with mental math).  We can say that 13.99 is the same as 10 + 3.99.  Now we can take it and multiply by 9 with the distributive property...

9(10 + 3.99) =
9*10 + 9*3.99 =
90 + 35.91 =

Answer:

The cost of 9 CD's is $125.91.

Step-by-step explanation:

The distributive property can be described as:

a(b+c)=ab+ac

Here given is that the cost of 1 CD is $13.99

We can write this cost as = 13+0.99

And the cost of 9 CD's can be calculated as:

9(13+0.99)

Further solving this we get

(9\times13)+(9\times0.99)

= 117+8.91=125.91 dollars

Therefore, the cost of 9 CD's is $125.91.
