But anyway, Sarah should score 75 runs in her sixth inning to reach an average of 50. To solve, first multiply 45 by 5 to reverse the division used to find her previous average. You should get 225. We want the score added to 225, the addend of them being divided by 6 to get 50, her average. Continue by putting your variables into an equation, then simplifying. Below, I distributed the division of the 6, then subtracted 37.5 from both sides of the equation, and finally multiplied both sides by 6 to get our final answer, a score of 75.
