1. Direct Labor costs
Took 1,260,000 and subtracted direct materials and direct labor to come up with $540,000 factory overhead. IS THIS CORRECT TO FIGURE THE FACTORY OVERHEAD? Took 540,000 direct labor divided by 540,000 factory overhead for 1%. IS THIS CORRECT? SHOULD I USE THE DIRECT LABOR COST OF $432,000 INSTEAD?
