Answer: $317,400
Explanation: The first step is to calculate the sales value
Sales = Unit sold × Price per unit
11500 × $77.00 = $885,500
calculation Total variable cost
i. Variable production cost = Units × variable production cost per unit
11500 × $39.70 = $456,550
ii. Variable selling and administrative cost = unit × variable selling and administrative cost per unit
11500 × $9.70 = $111,550
Total variable cost = Variable production cost + variable selling and administrative cost
Total variable cost = $456,550 + $111,550
= $568,100
Calculation of contribution margin
Contribution margin = Sales - total variable cost
= $885,500- $568,100
= $317,400
