The result from the 40-item Statistics exam Marion and Ella took already came out. Ella got 4 incorrect answers while Marion got 6 more than half the score of Ella. What is Marion's score?
Ella's score is 40 items - 4 items = 36 items.
Half of Ella's score is 36 items / 2 = 18 items.
So, Marion's score is 18 items + 6 items = 24 items.
