The total cost can be calculated as follows;
Total Cost = Fixed Cost + Variable Cost ----------------Equation 1
If x is the number of units produced then;
Total Cost = $3.00 x
Variable Cost = $2.50 x
Fixed Cost = $400
By applying the above given costs in the equation 1 to find the number of units produced;
$3.00 x = $400 + $2.50 x
Subtract the above Equation by $2.50 x, we get;
$3.00 x - $2.50 x = $400
$0.50 x = $400
Dividing the above equation by $0.50, we get;
x =
x = 800 units.
In mathematics, a variable (from Latin variabilis, "changeable") is a image and placeholder for any mathematical object. Mainly, a variable may also represent a variety of, a vector, a matrix, a feature, the argument of a characteristic, a hard and fast, or an element of a set. Algebraic computations with variables as if they were explicit numbers clear up more than a few troubles in a unmarried computation.
