\( \begin{aligned}

C_\mathrm{Total} = &~\sum_{t=1}^{T} R_\mathrm{0} - \frac{A}{2} + A T \\

=&~R_\mathrm{0}T - \frac{A}{2}T + A \frac{T(T+1)}{2}

= R_\mathrm{0}T + \frac{1}{2}A T^2

\end{aligned} \)

I've seen worse.

@kwf Neither of those screenshots shows it rendered-- did it eventually render for you?

Windell Oskay@oskay@qoto.orgSeems like it refreshes several times, and the last one isn't too beautiful. :(
