A neighborhood swim club charges a one-time fee of $25 to join and $85 each month. 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. Which variable is the independent variable?
A.t
B.n
C. There is no relationship between the variables. (MY ANSWER)
your equation should read:
t = 85n + 25
Doesn't the value of t "depend" on what you put in for n ??
So t would be the "dependent" variable, so that implies that .......
your choice of answer makes no sense.
You mean to say that the total t is not affected by the number of months involved?
Bet you that club won't last long.
To determine which variable is the independent variable, you need to understand the concept of independent and dependent variables.
In this scenario, the independent variable is the one that you have control over and can change freely. It is the input variable that affects the value of the dependent variable. On the other hand, the dependent variable changes in response to the independent variable.
Given the equation t = 85n + 25, where t represents the total amount spent and n represents the number of months of membership, we can see that the value of t depends on the value of n. The number of months of membership (n) is what you have control over, and by changing its value, you can determine the amount spent (t). Therefore, in this equation, the independent variable is B. n – the number of months of membership.
