Question

Hi can someone help me with my math hw? can you solve it on paper pls?

Answer 1

`\qquad \textit{Amount for Exponential Growth} \\\\ A=P(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &50000\\ r=rate\to 5\%\to (5)/(100)\dotfill &0.05\\ t=years\\ \end{cases} \\\\\\ A = 50000(1 + 0.05)^(t) \implies A=50000(1.05)^t \\\\[-0.35em] ~\dotfill`

`\stackrel{\textit{in 2017, 7 years later}}{A=50000(1.05)^7\implies A\approx 70355} \\\\\\ \stackrel{\textit{in 2020, 10 years later}}{A=50000(1.05)^(10)\implies A\approx 81444} \\\\\\ \stackrel{\textit{in 2030, 20 years later}}{A=50000(1.05)^(20)\implies A\approx 132664}`
