The correct Answer is:
To solve the problem, we need to set up equations based on the information provided about the number of students in each class at City High School. ### Step 1: Define Variables Let: - \( f \) = number of students in the freshman class - \( p \) = number of students in the sophomore class - \( j \) = number of students in the junior class - \( s \) = number of students in the senior class ### Step 2: Set Up Equations Based on the Problem From the problem statement, we can derive the following equations: 1. The sophomore class has 60 more students than the freshman class: \[ p = f + 60 \] 2. The junior class has 50 fewer students than twice the number of students in the freshman class: \[ j = 2f - 50 \] 3. The senior class is three times as large as the freshman class: \[ s = 3f \] ### Step 3: Total Students Equation The total number of students at City High School is given as 1,424. Therefore, we can write: \[ p + f + j + s = 1424 \] ### Step 4: Substitute the Expressions for \( p \), \( j \), and \( s \) Substituting the expressions we derived in Step 2 into the total students equation: \[ (f + 60) + f + (2f - 50) + (3f) = 1424 \] ### Step 5: Simplify the Equation Now, combine like terms: \[ f + 60 + f + 2f - 50 + 3f = 1424 \] This simplifies to: \[ 7f + 10 = 1424 \] ### Step 6: Solve for \( f \) Now, isolate \( f \): \[ 7f = 1424 - 10 \] \[ 7f = 1414 \] \[ f = \frac{1414}{7} \] \[ f = 202 \] ### Conclusion The number of students in the freshman class is \( \boxed{202} \).
