Question

Medal and fan reward!!!

Answer 1

To get L, first subtract 5 from 60 to get 55 because it takes you 5 minutes to set up the game, taking away the actual game-playing time.

Then, simply divide the number of minutes you have left (55 minutes) by the number of minutes it takes to complete a level (7 minutes) and you end up with the inequality:\[l \le55/7\]
The max amount of levels you can play is equal to 55/7, which is ~7 levels (you don't want to round up to 8 because you don't have enough time).
