Note that this is just to show you clearly how to solve the problem. On exam day you will not have this much time, so what is important? Knowing how many bonus bracelets (that will earn her $3) and that you want to condense these into as few days as possible without going above 205 bracelets per day.

So you will follow the first 2 steps, then you can just say “okay, so we will make 30 bonus bracelets on Friday, which means we have to split up the remaining 35 over two days so we do not go over our 205 maximum. The rest of the days will have only the minimum because we want as few as possible.”
