Complex Skill Costs

Well, not super complex. I'm trying to make the spells in my game cost a certain amount by spell 'level' so, at level 1, it would cost (The character's level * 11) * 0.10) or 10% of the characters's level times 11. 

I know I can do this in the damage formula, and I would love to be able to display the cost, but not necessarily a necessity, However, I'm trying to figure out how to make a minimum MP cost, let's say 25.

I'm using Yanfly's Skill Cost Manager, but, again, not really attached to it, and I want most of my skills to follow this formula, so I need to figure this out. Is anyone able to help?

[25,formula].max


this way if formula returns a cost less than 25, it will use 25 instead

Alright, I'm just a little confused.

Do I make it like: 

[25, a.mp = a.mp - (((a.level * 11) + 100) * 0.1))].max;

or like:

a.mp = a.mp - (((a.level * 11) + 100) * 0.1)); [25,formula].max;

or Am I completely off?

If it's already for the cost processing


a.mp -= [25,(((a.level * 11) + 100) * 0.1))].max


for the cost checking (to see if skill is usable or not)


[25,(((a.level * 11) + 100) * 0.1))].max

Oh, duurrr. I was putting it in the wrong spot. Thank you. Works fine now.
