A software development firm is contemplating outsourcing its customer support

operations to a call center in another country. The current annual fixed cost of running

an in$-$house customer support center is $$180,000,$ and the variable cost per customer

interaction is $$5.$ The outsourcing contract would cost the firm $$13$ per customer

interaction. Calculate the breakeven point between outsourcing and doing it themselves.

If they need to produce $1$ unit less than that number, is it cheaper to do it themselves or

outsource it$?$
