First of all, know that preserved lemons will keep for quite a while in the fridge. They are preserved, after all. Kept refrigerated, these lemons will keep for about a year, so don't feel that you have to rush to use them up before they go bad.You eat the whole lemon, rind and all â though I'd recommend removing the seeds first.hey are preserved, after all.

Growth Rate in the Present Value of Stock Formula. The growth rate used for calculating the present value of a stock with constant growth can be estimated as. Multiplying the retention ratio by the return on equity can then be reduced to retained earnings divided average stockholder's equity.
Your searching for a factor by which the initial value is to be multiplied to obtain the final value. If the initial value is 100 and the rate of change is 500%, the final value will be 600 (100 + 500), and it can be expressed as 600 = 100 * 6, therefore 6 is the grow factor. If the rate of change is -55%, we can perform the same calculation: initial value: 100 rate of change: -55% final value: 100 - 55 = 45 = 100 * 0.45 Therefore, the decay factor is 0.45. For an arbitrary rate of change R (expressed as %), the grow (or decay) factor F will be F = 1 + R/100
