3. Darren won Round 3 of the game. Sherri is wondering if she lost Round 3 by 5 points or by 25 points. Explain to Sherri how many points Darren won Round3 by and show the mathematics you used to justify your answer

It is required to find the number of points Darren won round 3 by.
From the table, it is given that Darren had 15 points in round 3, and Sherri had -10 points.
To find the number of points Darren won round 3 by, find the difference in their points for round 3:
[tex]15-(-10)=15+10=25[/tex]Hence, Darren won round 3 by 25 points.
Explain to Sherri that Darren won round 3 by 25 points and that this can be found by subtracting his points for round 3 from Darren's points from round 3.
