Step-by-step explanation:
The question asks to calculate the prime costs for Balmer Company in April 2018. Prime costs consist of the sum of direct materials used and direct labor. Within the given period, we know that the purchases of direct materials were $58,000 and direct labor costs were $82,000. To calculate the cost of direct materials used, we subtract the ending inventory of raw materials from the sum of the beginning inventory and the purchases:
- Beginning inventory of raw materials: $40,000
- Purchases of direct materials: $58,000
- Ending inventory of raw materials: $35,000
Cost of direct materials used = $40,000 + $58,000 - $35,000 = $63,000. We then add this to the direct labor costs to calculate prime costs:
Prime costs = $63,000 + $82,000 = $145,000.
Therefore, the correct answer for the prime costs for April is $145,000 (option a).
