The rate of change in this situation refers to how the cost of the health club membership changes over time.
To determine the rate of change, we need to identify the relationship between the cost and the time that has passed.
In this case, the $150.00 enrollment fee is a one-time cost and does not change with time. Therefore, it does not contribute to the rate of change.
The $25.00 monthly fee, on the other hand, does change with time. Each month, an additional $25.00 is added to the cost.
Therefore, the rate of change in this situation can be represented as $25.00 per month.
