Ahealth club charges $35 a month for membership fees. determine whether the cost of membership is proportional to the number of months. explain you reasoning

It is directly proportional. This is because as the number of months you pay for increases, the cost of the membership increases by the same amount. For example, if you pay for one month, the cost is 1 x $35. If you pay for two months, which is twice as much, the cost is also 2 x $35.
