<PRE><B>Question 400957</B>
Nancy has 2 printers available to her. Together, the 2 printers can print a document in 9 min. The Epson Stylus 850 can print the document in 12 minutes working by itself. How long would it take her EPson Stylus 500 to print the document working by itself?
---
Together rate: 1/9 job/min
---
E850 rate: 1/12 job/min
---
E500 rate: 1/x job/min
-----
Equation:
rate + rate = together rate
1/12 + 1/x = 1/9
---
Multiply thru by 36x to get:
3x + 36 = 4x
---
x = 36 min (time required for the E500 to do the job alone)
