Final answer:
The total contribution margin for next year will be $1,100,000.
Step-by-step explanation:
To calculate the total contribution margin for next year, we need to consider the changes in cost and sales volume. First, let's calculate the total variable cost per unit for next year. The variable cost per unit includes the direct materials, direct labor, variable manufacturing overhead, and variable selling costs. Based on the given data, the total variable cost per unit for next year will be $20 (direct materials) + $15 (direct labor) + $12 (variable manufacturing overhead) + $3 (variable selling) = $50.
Next, we need to calculate the total fixed cost per unit for next year, which includes the fixed manufacturing overhead and fixed selling and administrative costs. Based on the given data, the total fixed cost per unit for next year will be $30 (fixed manufacturing overhead) + $10 (fixed selling and administrative) = $40.
Finally, we can calculate the total contribution margin per unit for next year by subtracting the variable cost per unit from the selling price per unit. Applying the given data, the total contribution margin per unit for next year will be $160 (selling price) - $50 (variable cost) = $110. To find the total contribution margin for next year, we multiply the total contribution margin per unit by the expected sales volume, which gives us $110 * 10,000 = $1,100,000.
