c=60m
c/m = 60
they have told you that c=60m, so that for every minute, you get 60 copies.

This helped alittle but the answers were multiple choice
a. c
B. 60
C. m
D .m/c
That is why I thought the best answer was c. = m
Is this correct?

why not (B)?

How do you figure this out? I don't know how to do it? Can you please explain how you would get b? Did you just divide each side by m?
Thank you for your help

Basically, that is just what you do.
we are told that c=60m
that is, using the units,
copies = 60 * minutes
now divide by minutes because you want the rate (copies/minute)
copies/minutes = 60
also, you can think of it like this
c=60m
now, what happens if you take 1 more minute?
60(m+1) = 60m+60
That is, during the next minute you get 60 more copies.
