Question

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. Please help!
Thanks

Answer 1

c=60m
c/m = 60

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

Answer 2

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?

Answer 3

why not (B)?

Answer 4

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

Answer 5

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.
