If Louie scored 4 goals last night, his brother has scored 2 * 4 goals = 8 goals in each game. The total number of games Louie's brother has played in is 3 seasons * 50 games / season = 150 games. Louie's brother's total number of goals in the three seasons is 8 goals / game * 150 games = 1200 goals. Louie's total number of goals this season is 40 goals + 4 goals = 44 goals. Together, they have a total of 44 goals + 1200 goals = 1244 goals in the team.
The answer: 1244
