Solution
Solution Steps
To reapportion the 50 seats among the counties based on their populations, we can use the method of equal proportions. This method involves calculating a priority value for each seat allocation and distributing the seats one by one to the counties with the highest priority values until all seats are allocated.
Step 1: Initial Population Data
We start with the population data for each county:
Jefferson: 120,000
Clay: 62,400
Madison: 144,800
Jackson: 163,200
Franklin: 236,800
Step 2: Initial Seat Allocation
Each county is initially allocated 1 seat. Therefore, the initial seat allocation is:
Jefferson: 1
Clay: 1
Madison: 1
Jackson: 1
Franklin: 1
Step 3: Calculate Priority Values
We use the method of equal proportions to calculate the priority value for each county. The priority value for a county with population \( P \) and \( s \) seats is given by:
\[ \text{Priority Value} = \frac{P}{\sqrt{s(s+1)}} \]
Step 4: Allocate Remaining Seats
We allocate the remaining 45 seats (since 5 seats are already allocated) one by one to the county with the highest priority value at each step. The final seat allocation after distributing all 50 seats is:
