A machine at Staples photocopies 12 ΒΌ pages per minute. If the machine runs 700 minutes, how many pages will be photocopied?

let
v = 12 1/4 pages per minute = (12*4 + 1)/4 = 49/4 pagers per minute is the rate of the machine
t = 700 min the time that the machine runs
s = the number of pages photocopied
since v = number of pages / the time needed to photocopy those pages
v = s / t => s = v*t
s = (49/4)*700
s = 8575 pages
8575 pages will be photocopied.
