Let N be the number of players in a team.
As each team can have numbers of players ranging from 3 to 5, so
[tex]3\leq5\ldots\ldots.1[/tex]
Let P be the points scored by one player in one round of the game.
As each player can score up to 10 points in each round of the game, so
[tex]0\leq P\leq10\ldots\ldots..2[/tex]
There are 5 members in the team formed by Elena.
So, points earned by 5 players in 1 round = 5P
From equation (2), the range is
[tex]0\leq5P\leq50[/tex]
Hence, the points earned by Elena's team is ranging from 0 to 50.
Therefore, If each played misses 1 point, then,
Points earned by 1 player in 1 round = 10-1 = 9
Hence, the number of points earned by Elena's team if each player misses one point will be
[tex]9\times5=45[/tex]
