Answer:
20 represent the cost per variable inputs
Step-by-step explanation:
C(x) = 20(4x) + 500
Total cost is the addition of variable cost and fixed cost
Fixed cost are cost that do not change during the production process such as machinery, furnitures and fittings.
Variable cost are cost of production that changes with production process such as cost of labor, cost of raw materials.
C(x) = 20(4x) + 500
C(x) represent the total cost
20(4x) represent the variable cost
500 represent the fixed cost
From the variable cost 20(4x)
20 represent the cost per variable inputs
When solving for a variable in an equation, get it separated from the others onto one side typically the left hand side and rest onto the opposite side usually the right hand side.
V = x / t
First, let us get the 't' variable out of denominator position and then it will be easier to work with.
V * t = (x / t) * t
Why did I multiply each side by 't' and not just the "x / t" expression? That is because every operation we do on one side, we must also do on the opposite side.
Okay, now we get the following equation.
V * t = x
We removed the 't' variable from denominator and in fact, it doesn't even exist anymore on the right hand side!
To complete this question, all we have to do is divide each side by 'V' and we are done!
(V * t) / V = x / V
Comes out to:
t = x / V
And there is your answer! Hope this helps with your adventure in learning Algebra!
