In the given scenario:
-
Initial Value (b): This is the cost incurred before any rides are taken. Since the only fixed cost mentioned is the entrance fee, the initial value is: \[ b = 12 \text{ (the entrance fee)} \]
-
Rate of Change (m): This represents how much the total cost increases with each additional ride taken. Since each ride ticket costs $2, the rate of change is: \[ m = 2 \text{ (the cost per ride)} \]
Therefore:
- The initial value is \( b = 12 \)
- The rate of change is \( m = 2 \)
