Question

I will send a picture of the equations because if I type it here it won't make sense.

Answer 1

`\begin{gathered} P=25000e^(0.03t) \\ P=50000 \\ 25000e^(0.03t)=50000 \end{gathered}`
`\begin{gathered} \text{divide both side by 25000} \\ e^(0.03t)=(50000)/(25000)\Rightarrow e^(0.03t)=2 \\ \text{Take the N}aturalLogarithm\text{ of both side: } \\ \ln e^(0.03t)=\ln 2 \\ 0.03t=\ln 2 \\ t=(\ln 2)/(0.03) \end{gathered}`

Hence option A is the correct answer
