Kim's softball team is playing in the championship game. They are losing by a score of 17 to 6. There are 4 innings to go. Kim wants to know how many runs her team needs per inning to win the game if the other team does not score. (Each run is worth 1 point.) Let rrr represent the number of runs per inning. Assume that the team scores the same number of runs per inning, and write an inequality to determine the number of runs per inning needed to win the game.
