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.
The chain-weight real growth rate is then computed as the geometric mean of these two fixed-weight real growth rates (row 13). The next step is to choose a base year and calculate real GDP figures for each year by using the chain-weight real growth rates.In Figure 1, year 3 is chosen as the base year, so nominal GDP in year 3 is declared chain-weight real GDP.he BEA does not directly calculate chain-weight GDP using an equation like (1) , but the actual method employed by the BEA to calculate real GDP growth is also probably impractical at the intermediate level.
