I'm sure there are others on here who could explain it far better than I can, but I'll try anyways:

You take the intial boost, which is 2.0 (or 100%), and then multiply it by the "when performing a Super Attack" buff, which if 1.5 (or 50%).

2.0 x 1.5 = 3.0, so the total boost would be 200%.

However, that Vegeta gets more ATK & DEF, up to 35%, per DB Heroes allies. This buff is another start-of-turn buff, so you'd take the original 100% and add 35% to it.

2.35 (135%) x 1.5 = 3.525, so the total boost is  252.5%
