Let the batter's career average before her 17th inning be "x" runs per inning.
After her 17th inning, her career average increased by 3 runs, so her new average is (x + 3) runs per inning.
In the first 16 innings, she scored a total of 16x runs.
After her 17th inning, her total runs scored became 16x + 87 runs.
Now, we can set up an equation:
(16x + 87) / 17 = (x + 3)
Now, solve for x:
16x + 87 = 17x + 51
87 - 51 = 17x - 16x
36 = x
So, her career average before the 17th inning was 36 runs per inning, and her new average after the 17th inning is (36 + 3) = 39 runs per inning.
