A plumber charges a visitation fee of $60 and $45 per hour for time worked. If h is the number of hours worked and t is the total charge for completed work, then the variables are related by the equation t = 45h + 60. Which variable is the independent variable?

Respuesta :

H is the independent variable because t depends on h.

The independent variable is h because t always changes when h changes but h doesn't change when t changes. The value of t depends on h. The value of h does not depend on t. So that mean h is the independent variable.
