Here's how I did it:

Explanation:

First, we know that 19.99 is almost 20, or 0.01 away from it to be exact.

So our expression can be rewritten as 6(20-0.01).

Now, we use the distributive property to simplify that:

Following this image, we know that:
color(blue)(6(20-0.01) = (6 * 20) + (6 * 0.01) = 120 + 0.06 = 120.06)

So the answer is 120.06.

Hope this helps!
