If the total number of commuters to County W is twice the number to County Z, and if the average number of vehicles that transport commuters daily to County W is 30,000, what is the approximate average number of vehicles that transport commuters daily to County Z?
Show Hint
- \( 12,000 \)
- \( 15,000 \)
- \( 18,000 \)
- \( 27,000 \)
- \( 36,000 \)
The Correct Option is B
Solution and Explanation
Step 2: Vehicles in county W = 30,000; assume vehicle occupancy rates (from graph) are similar, e.g., County W ~1.6, County Z ~1.7, but focus on the commuter ratio.
Step 3: If vehicles scale with commuters (no occupancy rate given), vehicles to Z = \( \frac{30,000}{2} = 15,000 \).
Step 4: (B) 15,000 fits the approximation of the ratio.
