Answer 2

Problem Analysis

We are given that three workers earned a total of 800 UAH. The first and second workers earned 503 UAH together, while the second and third workers earned 555 UAH together. We need to determine how much each worker earned individually.

Solution

Let's assume that the first worker earned x UAH, the second worker earned y UAH, and the third worker earned z UAH.

From the given information, we can form two equations:

Equation 1: x + y = 503 Equation 2: y + z = 555 We also know that the total earnings of all three workers is 800 UAH:

Equation 3: x + y + z = 800

To solve this system of equations, we can use substitution or elimination.

Let's solve it using the substitution method:

From Equation 1, we can express x in terms of y: x = 503 - y

Substituting this value of x into Equation 3, we get: (503 - y) + y + z = 800 503 + z = 800 z = 800 - 503 z = 297

Now, substituting the value of z into Equation 2, we get: y + 297 = 555 y = 555 - 297 y = 258

Finally, substituting the values of y and z into Equation 1, we get: x + 258 = 503 x = 503 - 258 x = 245

Therefore, the first worker earned 245 UAH, the second worker earned 258 UAH, and the third worker earned 297 UAH.

Answer

Each worker earned the following amounts: - The first worker earned 245 UAH. - The second worker earned 258 UAH. - The third worker earned 297 UAH.
