**Katie**, Thursday, April 17, 2008 at 8:10pmHow would you set it up? Would it be (72/2) + (72/1.5)= (70/x)? we didn't do examples in class

**Damon**, Thursday, April 17, 2008 at 8:45pmnew --> 36 copies/min

old --> n copies/min

new + old = (n+36) copies/min

(n+36)copies/min * 1.5 min = 72 copies

1.5 n + 54 = 72

1.5 n = 18

n = 12 copies/min

12 copies/min * t = 70 copies

t = 35/6 = 5.83 min

**Damon**, Thursday, April 17, 2008 at 8:49pmI wrote out all those copies/ min and such for a reason. In problems like this if you keep track of the units, it is hard to go far off course.
