You are the program manager for your organization and you're trying to determine if you buy or build a software solution for your organization. If you build the solution it'll cost you $75,000 to create and it'll cost you

$12,000 per month to support. If you hire a vendor they can build the solution for $63,000 but their solution will cost you $15,500 per month to support. How many months would you have to use your in-house solution to equate to the cost of the vendor's solution?
