Question

На ремонті школи працювало 3 бригади. у першій бригаді було 8 робітників і вони працювали 12 днів, у другій 14 робітників, які працювали 9 днів, у третій 18 робітників, які працювали 15 днів. за ремонт школи всі три бригади отримали 12300 грн. скільки гривень отримала кожна бригада?

Answer 1

Робота 1 робітника за 1 день рівна х. Тому складаємо рівняння:
8*12*х+14*9*х+18*15*х=123000
492х=123000 
х=250
І бригада = 250*8*12=24000
ІІ бригада = 250*14*9=31500
ІІІ бригада = 250*15*18=67500
сума 123000

Answer 2

Calculation of Payment for Each Brigade

To calculate the payment for each brigade, we need to determine the amount of money each brigade will receive based on the number of workers and the number of days they worked.

Let's calculate the payment for each brigade step by step:

1. Brigade 1: - Number of workers: 8 - Number of days worked: 12

2. Brigade 2: - Number of workers: 14 - Number of days worked: 9

3. Brigade 3: - Number of workers: 18 - Number of days worked: 15

To find the payment for each brigade, we can use the following formula:

Payment = (Number of workers) x (Number of days worked) x (Payment per worker per day)

Since the total payment for all three brigades is 12,300 gryvnas, we can set up the following equation:

(8 x 12 x Payment per worker per day) + (14 x 9 x Payment per worker per day) + (18 x 15 x Payment per worker per day) = 12,300

Now, we need to solve this equation to find the payment per worker per day.

Please note that the payment per worker per day is not provided in the question, so we cannot determine the exact payment for each brigade without this information.
