4. Gemini Production uses a job costing system with two overhead pools: Overhead A, allocated at a rate of $45 per direct labor hour; and Overhead B, allocated at a rate of $100 per machine hour. Gemini just completed Job A45, which used $500,000 in direct materials costs, $80,000 in direct labor costs for 8,000 hours, and 2,500 machine hours.

Calculate the cost of Job A45 before accounting for spoilage and rework.
