I don't know where you are going to find an account at 19.9%. I'd like one of those.
1800(1+0.099)^45 = $${\mathtt{1\,800}}{\mathtt{\,\times\,}}{\left({\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\mathtt{0.099}}\right)}^{{\mathtt{45}}} = {\mathtt{125\,941.442\: \!752\: \!763\: \!295\: \!979\: \!9}}$$
There you to $125,941.44
