In a Geometry exam, Madeline got 2 mistakes which are half as many mistakes as Leo. Brent scored 25 and has 1 more mistake than Leo. What is Madeline's score?
Let's be accurate as possible and think first.
28
Leo got 2 x 2 = 4 mistakes.

So, Brent got 4 + 1 = 5 mistakes.

This means that 25 + 5 = 30 is the perfect score.

Hence, Madeline got a score of 30 - 2 = 28.

.

Final answer: 28
