Explanation:
Calculation to determine what The Gross margin for September was
First step is to determine the variable costs
Variable costs= (317 * 7,100) + (44*7,100) + (22*7,100)
Variable costs= 2,250,700 + 312,400 + 156,200
Variable costs= $2,719,300
Now let determine the Gross margin
Using this formula
GM=Sales-VC
Let plug in the formula
Gross margin = (682 * 7,100) - 2,719,300
Gross margin = $2,122,900
Therefore The gross margin for September was:$2,122,900
