Custom Formula based on option

Hi,

I am new to using opencart (2.1.0.2) and I am wanting to put in a custom formula on each product based on if they select the only checkbox (which created through options) http://cms-test2.dynamic-stationery.com ... duct_id=63

So the formula would be setup fee ($121) x quantity ordered @ $0.88 + $20 e.g for 50 books = 121 + (50 x .88) + 20 = $185 + the total of the actual books, so complete total would be 892.85

hopefully this makes sense

Cheers,
