A fitness club charges $25 per month as well as a one-time $80 fee of all new members which equation represents the cost in dollars, c, for a new member who prepays for m month

Answer: So if you want to find the total cost (c) for a certain number of months (m) and it costs $35 per month, you just need to multiply the number of months by the cost per month. So

35m=c

If you want to see the units cancel

($35/month) (months) = $

The months will cancel out, and you will be left with total dollars.

Not sure about the second part of your question, but if you wanted to figure out how much it would cost to be a member for 6 months, you would just plug in 6 for m.

35 (6) = c

c=210

So $210
