Hi
What does "the system will pay for itself within a few years" mean?
"The terminal, known as a minitel, will allow online access to a data base containing all the telephone numbers in France, thus eliminating the need for printing and distributing expensive telephone books. It will also vastly reduce the need for information operators who do nothing but give out telephone numbers all day. It has been calculated that the system will pay for itself within a few years."
Within a few years, the amount of money earned by the system, and/or the amount of money saved as a result of not having to print telephone directories and not needing so many operators, will equal the cost of installing the system.
