The table shows a golfer's scores for four rounds of a recent US Women's Open. Her total score was even par. What was her 3rd round score?

Answer:
The value of s is plus 2.
Step-by-step explanation:
Par is the number of strokes that a golfer requires to complete a hole.
"Even par" is the term used ,when a golfer uses the same number of strokes as a hole's par rating means no more or no less.
Here, we will equate all the scores to zero, to get the value of s.
[tex](-1)+(-3)+(s)+(+2)=0[/tex]
=> [tex]-1-3+s+2=0[/tex]
=>[tex]-4+s+2=0[/tex]
=> [tex]s=4-2=2[/tex]
Therefore, [tex]s=+2[/tex]
