Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.Substituting r = 0.01 and n = 240 into the above formula, we can get:\begin{align*}
&=1.01^{240}The following is to calculate the increase of 240 trading days according to the daily increase of 2%, and calculate it through the calculator, 1.02 {240} \ approximate 115.8887.\end{align*}
Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.If it rises by 1% or 2% every day, how much will it increase in 240 trading days a year?
