RNF = (85% x 15 Million) - (25% x 15 Million) - (6% x 115 Million) (1 - 0.5)

I keep trying to figure this out and I cannot get the right answer. I believe the answer to be

= 5.55 Million well at least that's what the instructor says.

I do not come up with that, so I need to know what I am doing wrong. Thank You
