Explanation:

Graduation rate is calculated as (number of graduating seniors / total number of seniors) * 100%. So for each school, we need the number of graduating seniors (already given) and the total number of seniors at that school. The total number of students in the school is not relevant as we are only concerned with seniors.

Answer:

• the total number of seniors at Centerville High School
• the total number of seniors at Westville High School
