Question

Бригада рабочих по ремонту подвижного состава отработала 5 дней, общее отработанное время составило 78 часов. Оплата за объем выполненных работ составил 50 000 рублей.
КТУ работников бригады следующий:
- автослесарь = 1,2; электромонтер = 0,7;
слесарь по ремонту подвижного состава = 1.5.
Рассчитайте заработную плату каждого работника

Answer 1

Ответ:

Now we have two equations:

x + y + z = 78

-0.3x - 0.8y = 49,883

Solving these equations simultaneously will give us the values of x, y, and z, which represent the number of hours worked by each employee. Once we have these values, we can multiply them by their respective KTU values to calculate their salaries.

Объяснение:

To calculate the salary of each employee, we need to determine the number of hours worked by each employee and then multiply it by their respective KTU (Coefficient of Tariffication Unit) values.

Let's assume the car mechanic worked for "x" hours, the electrician worked for "y" hours, and the rolling stock repairman worked for "z" hours. We can set up the following equations based on the given information:

x + y + z = 78 (total hours worked)

1.2x + 0.7y + 1.5z = 50,000 (total payment in rubles)

To solve these equations, we can use substitution or elimination method. Let's use substitution:

From the first equation, we can express z in terms of x and y:

z = 78 - x - y

Substituting this value into the second equation:

1.2x + 0.7y + 1.5(78 - x - y) = 50,000

Simplifying the equation:

1.2x + 0.7y + 117 - 1.5x - 1.5y = 50,000

-0.3x - 0.8y = 50,000 - 117

-0.3x - 0.8y = 49,883

Now we have two equations:

x + y + z = 78

-0.3x - 0.8y = 49,883

Solving these equations simultaneously will give us the values of x, y, and z, which represent the number of hours worked by each employee. Once we have these values, we can multiply them by their respective KTU values to calculate their salaries.
