elena-14-01-66 [18.8K]

In order to calculate the value of t, we can use the given formula with the values P = 6000, A = 2P and i = 11% = 0.11:

\begin{gathered} 2\cdot6000=6000\cdot e^{0.11t}\\ \\ 2=e^{0.11t}\\ \\ \ln2=\ln e^{0.11t}\\ \\ 0.693147=0.11t\\ \\ t=\frac{0.693147}{0.11}=6.3 \end{gathered}

Therefore the time needed is t = 6.3 years.
