To use a pocket calculator, it takes fewer hours (15 hours) and more capital ($20). To use a pocket calculator and paper and pencil, it takes fewer hours (7 hours) and more capital ($25). To use a PC, it takes fewer hours (1 hour) and more capital ($1,000). No method uses more of both resources (time and capital) than any other method. So all methods are technologically efficient. ................
