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!

  • math- please help -

    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?

  • math- please help -

    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

    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.
