Final answer:
The total manufacturing costs for Job No. 176 is $450,000.
Step-by-step explanation:
To find the total manufacturing costs for Job No. 176, we need to calculate the direct labor cost and overhead cost. The direct labor cost is the basis for calculating the overhead cost. Since the overhead is applied at 150% of the direct labor cost, we can calculate the direct labor cost by dividing the manufacturing overhead by 150% (or 1.5). In this case, the manufacturing overhead is $180,000, so the direct labor cost is $180,000 / 1.5 = $120,000.
Now we can calculate the total manufacturing costs for Job No. 176 by summing the direct materials cost, direct labor cost, and manufacturing overhead.
Total manufacturing costs = Direct materials cost + Direct labor cost + Manufacturing overhead
Total manufacturing costs = $150,000 + $120,000 + $180,000 = $450,000.
