At a local fitness center, gym members pay $3 per workout with an annual membership fee of $140. Non-members pay $10 per workout

sleet_krkn [62]

Answer:

Yes the membership is worth it. If you have a membership you will pay $140 for the whole year. Then, it is $3 everytime you workout and if you plan on working out 2 times a month the total will be $72 dollars. So $72 + $140 is $212 yearly. If you don't get the membership you pay $20 a month because you will workout twice a month. So, 20 times 12 is $240. It may seem like it's not worth it but it actually comes out cheaper. So, yes I do think the membership is worth it.

Step-by-step explanation:

Hope you find this helpful. If you have questions feel free to ask.
