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. Thank you

Respuesta :

you would pay $420 at the end of the year because you do 12×35 or you could add 35 12 times
The cost of membership is 35 times the amount of months.  As there is a ratio between the total cost of membership and the amount of months purchased, the cost and the time are indeed proportional.
