(buyable)
i dont know whether you want to do this as a cost, an effect or something else, but you may be able to put this into the relevant function
return new Decimal(1.12).pow(x).times(Decimal.dOne.add(x)).times(10)
above asking a new question whenever you need to compute another expression, i suggest you read the Decimal.js documentation decimal.js API
or a tutorial to javascript functions JavaScript Functions
