Metro - rail fares
· Each passenger needs a fare - card. (Up to two children under 5 may travel free with a paying customer.)
· Fares are based on when and how far you ride. Pay regular fares on weekdays 5:30 -9:30 a. m. and 3:00 -7:00
· P.m. Pay reduced fares at all other times.
· Large maps in each station show fares and travel times. Please ask the station manager if you have any questions.
· Fare - card machines are in every station. Bring small banknotes because there are no change machines in the stations and fare - card machines only provide up to $ 5 in change ( in coins). Some machines accept credit
Text 3 If open-source software is supposed to be free, how does anyone selling it make any money It’s not that different from how other software companies make money. You’d think that a software company would make most of its money from, well, selling software. But you’d be wrong. For one thing, companies don’t sell software, strictly speaking; they license it. The profit margin on a software license is nearly 100 percent, which is why Microsoft gushes billions of dollars every quarter. But what’s the value of a license to a customer A license doesn’t deliver the code, provide the utilities to get a piece of software running, or answer the phone when something inevitably goes wrong. The value of software, in short, doesn’t lie in the software alone. The value is in making sure the soft ware does its job. Just as a traveler should look at the overall price of a vacation package instead of obsessing over the price of the plane ticket
