In the provided image, you're asked to form a system of equations related to a cost function. Let me break down the details given in the task:

• The task involves a cost function for production, which is related to the number of units produced (denoted as ME).
• The variable costs are given as 680 GE (which is the variable cost per unit).
• The total cost function is connected to the variable and fixed costs.
• The goal is to construct an equation system from the provided details. Based on the given conditions:

1. The costs when 10 units are produced amount to 1,250 GE.
2. The cost function should show the cost per unit when 10 units are produced (which gives a unit cost of 125 GE per unit).
3. The cost function's form involves fixed costs and variable costs per unit.

Step-by-step:

Let the total cost function be: $K(x) = F + V \cdot x$ where:

• $K(x)$ is the total cost for producing $x$ units,
• $F$ is the fixed cost,
• $V$ is the variable cost per unit, and
• $x$ is the number of units produced.

From the information provided:

• At $x = 10$, $K(10) = 1,250$ GE, and the variable cost per unit $V = 680$.
• The cost per unit for 10 units is given as 125 GE.

So, we can form the following equations:

1. $F + 680 \cdot 10 = 1,250$ (Equation for total cost when producing 10 units).
2. $K(x) = F + 680 \cdot x$ (General form of the cost function).

Solving:

For equation (1): $F + 6,800 = 1,250 \quad \Rightarrow \quad F = 1,250 - 6,800 = -5,550$

Now we have: $K(x) = -5,550 + 680 \cdot x$
