Resistant Protection? My brain hurt

[zombietots]

I am looking at the Brick on pg. 252 of the Champions book, and one of the powers is "Super Tough Body 28pts." I went with this because I took the Basic Brick characteristics 28 PD/ 28 ED but I just don't get the math. 

First, I thought it was a power from 6E1 pg 275 and I did 3 x 28 = 84 (Because 3CP/ 2pts), so that wasn't right. Then I saw the advantage on 6E pg 147 where I find Resistant (+½) but I can't find how it adds up. 

 

Is it 28ED/28ED = 56 divided by 2 x 3 or 28 x 3 = 84 with advantage (+1/2) = 42.

 

I don't understand how you get a point cost of 28 for 28PD/28ED

The +1/2 Resistant Advantage is being applied to the character's PD & ED Characteristics.  To do this, you figure out the cost of the Characteristics (as you note, that would be 56 points for 28 PD/28 ED), apply the Advantage, and then pay for the difference (since you've already paid for the Characteristics).

56 * (1 + 1/2) = 84 points total.  84 - 56 = 28 points that you would pay to make the 28 PD/28 ED fully Resistant.
