Step 1: Review the formula of compound interest final value.\begin{align*}
Therefore, according to the daily increase of 1\%, the increase is about 989.26\% after 240 trading days.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.This means that after 240 trading days, the overall increase multiple is about 115.8887 times, which is converted into the form of increase percentage, and the increase is (115.8887-1)×100\% = 11488.87\%.
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.&=1.01^{240}Therefore, according to the daily increase of 1\%, the increase is about 989.26\% after 240 trading days.
