Since the Davis Medical Center usually has a weight 4 times that of Woodland Hospital, it means that the Davis Medical Center weight is 4 times larger than the Woodland Hospital weight.
Let's assume the weight of Woodland Hospital is "x".
Therefore, the weight of Davis Medical Center would be 4x.
To determine where the ambulance should park, we need to compare the weights. The ambulance should park at the location with the higher weight because it indicates a higher average number of emergent patients.
If 4x > x, then the ambulance should park at Davis Medical Center.
Simplifying the inequality, we have:
4x > x
Subtracting "x" from both sides:
3x > 0
Dividing both sides by 3:
x > 0
Since "x" represents the weight of Woodland Hospital, and weight cannot be negative, we can conclude that the ambulance should park at Davis Medical Center.
Therefore, the ambulance should park at Davis Medical Center.
