Thomasjohn, The first question of yours is answered a bit earlier

For the maximum profit, for every the time it took for 2 long= the time for 3 short. However 2 long was more profitable than 3 short, so the answer was the one that was like 540. Cant remember it too well.

For the two equations, when you put them in slope-intercept form you get one with a positive slope and one with a negative slope, so there’s an intersection only.
