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 think first. Chain of thought:
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.
Therefore, the answer is 28.
