Does anyone know how to solve the very last question (labeled Question #1) on Yekan's slides for week 8? It's the one on half life but idk what equation he used to solve for the number of days.

There is no real equation, what you need is to figure out how many half-live cycles it takes to get 3g from 768g. Since it took 8 cycles and each cycle is 50 days, you can multiply them together to get the total days travelled, which is 400.
