Step-by-step explanation:
I really do hope I understood you correctly. I figured that the rule would have to be added to each point. If those are wrong, try subtracting the rule.

Answer:
80
Step-by-step explanation:
So I here's my thought process on this:
200 divided by 2 is 100
100 - 40% is 60, leaving 40 behind.
So double that and it would be:
200 - 40% is 120
200 - 120 = 80
80% is the answer.
