Here is what I got (Red represents my work, blue represents to follow which steps and highlighter represents what the answer is):
Answer: 
Step-by-step explanation:
Although you did not provide the inequalities, the only inequality that can represent the number of points Cedric's basketball team scored in their last game is the one shown below:
Let's call the number of points Cedric's basketball team scored in their last game:
.
You know that Cedric's basketball team scored fewer than 76 points in their last game. "Fewer than" means "less than", which is represented with the symbol < .
Therefore, you can represent the number of points Cedric's basketball team scored in their last game with the following inequality:
