Answer:

n is the independent variable.

Explanation:

A neighborhood swim club charges a one-time fee of $25 to join

His monthly charges = $85

If n is the number of months of membership and t is the total amount spent, then the variables are related by the equation
t = 85n - 25.

In the given equation t is the dependent variable.Since it depends on n.

Total cost will depend on the number of the months for which you have joined the club

n is the independent variable .Since it it does not depend on any other variable like t

Because t total cost depends on n .

Hence Option A is correct : n is the independent variable.
