Answer:

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!
