Question 416595
A copy machine has a purchase cost of $1200 and has an estimated page cost of 2$ per page.
 What is the minimum number of pages that should have to be copied before the
 purchase of the copy machine would be more cost effective than renting a machine at a cost of 5$ per page? 
:
Let n = number of pages that would make buying a copy machine cost effective
Rent cost greater than own cost
5n > 2n + 1200
5n - 2n > 1200
3b > 1200
n > {{{1200/3}}}
n > 400 pages, more cost effective to own the machine
:
:
Check the cost when 401 pages are printed
Rental: 5*401 = $2005
Own: 2*401 + 1200 = $2002
