In a particular card game, the minimum score a player can achieve in a single game is 20, and the maximum score possible in a single game is 52. if a player plays three games and scores a total of 141 points, what is the least number of points that the player could have scored in one of the games?

So if we want to know the least amount, we first want to assume the other two games both had a score of 52, so we can say the last one had the least possible.

So if both got 52, the total points would be 104, for two games of 52 points. Since we want 141 points, we therefore want 37 more points to reach 141.

So the least amount of points a player could've scored in one of the games was 37.
