Performance Task 2 (3 points)
In a football game, a team can score points the following ways:
Touchdown (no extra point) = 6
Touchdown (with 1 extra point) = 7
Touchdown (with 2 extra points) = 8
Field Goal = 3
Safety = 2
A team can achieve 22 points in one game by getting two touchdowns with one extra point, two field goals, and one safety.
(7 x 2 ) + (3 x 2) + ( 2 x 1) = 22 points
Write a numerical expression to show how the team could score 30 points in a different game.
