a copy machine makes c copies in m minutes according to the equation c=60m. what is the unit rate of copies per minute?
I think it is m but not sure, can you help me understand how to figure out this equation.
Thanks

math 
Reiny,
Suppose you were to actually put a number in for m
e.g.
A copy machine makes 120 copies in 4 minutes, what is the unit rate of copies per minute
Wouldn't it be 30 copies per minute ?
What did we do ?
We divided 120 by 4.
so if it makes c copies in m minutes, then the
unit rate would be c/m copies per minute.
