Jenny got a 95 on her paper. Jason's grade was 25 points less than Jenny's, and Bob's grade was equal to half of Jason's grade. What was Bob's grade? Let's be accurate as possible.
First find Jason's grade by subtracting 25 from Jenny's grade: 95 - 25 = 70. Then divide Jason's grade by 2 to find Bob's grade: 70 / 2 = 35.
The answer: 35.
