please answer this question as an paragraph. do not need to give a specific number or solve it. just the general idea are fine. follow fhe example that is given already.

Please give one example of real-life problem that can be formulated as a linear programming problem. Make sure you have a clear statement about the background, the decision variables, objective function and constraints. You do not need to give a specific number or solve it, only the general ideas are fine. For example, everyone uses Google Maps. The underlying algorithm is to minimize the time from your current location to the destination. The decision variables can be you need to choose one of the routes like highway or local. The constraints might be avoid toll, avoid ferry and so on
