Question

A health club charges 35 a month for membership fees. Determine whether the cost of membership is proportional to the number of months . Explain your reasoning .

Answer 1

I believe the equation represented here is proportional because it has a fixed or "unit rate" which does not change but rather remains constant. This meaning any number of months can be substituted for higher or lower values as the input and the output would not cease to be multiplied by 35 regardless of the input value.
