За решаване на задачи, свързани с извършване на определена
работа използваме следната зависимост:
A = N. t
А – количеството свършена работа
t – времето, за което е свършена работата
N – нормата (производителността), т.е. работата за единица време

Зад.1/ стр.94
Апо план< Ад
Апо план +80 = Ад
24х +80 = 22(х+5)
24х +80 = 22х +110
24х -22х = 110 – 80
2х = 30
х = 30:2
х = 15, х ∈ ДС
Отг.: Дневната норма по план е 15 автомобили
