How to assign correct profit margin?

[shabbysquire]

I need to add a certain profit margin to various prices, i.e.

£1 - £20 Add £2 profit;
£20.01 - £50 Add £3.50 profit;
£50.01 - £100 Add £5 profit.

I'm able to calculate the profit ok, but what's the best way to check the price brackets? i.e. check if £17.55 will go into £1 - £20?

use the Javascript and logic judge action.
the var:y can take as your profits.
hope to see some more better method in following.
var x={-Variable.price_old-}; var y=2; x+y;
var x={-Variable.price_old-}; var y=3.5; x+y;
var x={-Variable.price_old-}; var y=5; x+y;

My suggestion when things is coming to prices is you take and convert any price in cents thats price x 100

Then just use checking by ranges and add your needed profit.
