The total cost of ownership (TCO) model can be used to analyze direct and indirect costs of implementing specific technology. Costs include hardware and software acquisition, installation and training, support and maintenance, infrastructure, downtime, and costs of space and energy.

When all these cost components are considered, the TCO for a PC might run up to three times the original purchase price of the equipment. Hardware and software acquisition costs account for only about 20 percent of TCO, so managers must pay close attention to administration costs to understand the full cost of the firm's hardware and software, and hidden costs such as costs for support staff, downtime, and additional network management

Imagine that you wish to exchange one currency for another. You realize that instead of directly exchanging one currency for another, you might be better off making a series of trades through other currencies, winding up with the currency you want. Suppose that you can trade n different currencies, numbered 1, 2, ..., n, where you start with currency 1 and wish to wind up with currency n. You are given, for each pair of currencies i and j , an exchange rate $$ r_{ij} $$ , meaning that if you start with d units of currency i, you can trade for $$ dr_{ij} $$ units of currency j. A sequence of trades may entail a commission, which depends on the number of trades you make. Let $$ c_k $$ be the commission that you are charged when you make k trades. Show that, if $$ c_k = 0 $$ for all k = 1, 2, ..., n, then the problem of finding the best sequence of exchanges from currency 1 to currency n exhibits optimal substructure. Then show that if commissions $$ c_k $$ are arbitrary values, then the problem of finding the best sequence of exchanges from currency 1 to currency n does not necessarily exhibit optimal substructure.
