Final answer:
The total cost of making chairs is $16,000.
Step-by-step explanation:
To determine the total cost of making chairs, we need to consider the direct materials, direct labor, and allocated overhead costs. The direct materials cost for chairs is $4,000, while the direct labor cost is $12,000. Based on the given information, there is no specific mention of overhead costs allocated to chairs. Therefore, the total cost of making chairs can be calculated as $4,000 + $12,000 = $16,000.
