Answer:
n is the independent variable.
Step-by-step 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
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.
