Final answer:
The question involves the growth of City Fitness's membership over time, which can be modeled using an exponential function in Mathematics.
Step-by-step explanation:
In this question, we are dealing with the growth of City Fitness's membership over time. This type of growth can be modeled using exponential functions in Mathematics. Specifically, the membership growth can be represented by the equation:
Membership = Initial Membership x (Growth Factor)^(Number of Years)
In this case, the initial membership is 840, and the growth factor is (1/4). So, plugging in these values into the equation, we get:
Membership = 840 x (1/4)^n
where 'n' represents the number of years. This equation can be used to calculate the membership of City Fitness after a certain number of years.
