\[a = 2000\ (рублей);\]
\[p = 3\ (\%);\]
\[t = 2 + \frac{7}{12} = \frac{2 \bullet 12 + 7}{12} =\]
\[= \frac{31}{12}\ (года).\]
\[Сумма\ денег\ на\ счете\ в\ конце\ \]
\[S = a\left( 1 + \frac{p}{100} \right)^{t};\]
\[S = 2000 \bullet \left( 1 + \frac{3}{100} \right)^{\frac{31}{12}} =\]
\[= 2000 \bullet (1,03)^{\frac{31}{12}} \approx\]
\[\approx 2000 \bullet 1,079351 \approx 2158,7.\]
\[Ответ:\ \ примерно\ 2158\ рублей\ \]
