Use the Distributive Property to find the price of 9 CDs that cost $13.99 each.
Andreas93 [3]
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 =
