Estimated factory overhead and direct labor time for the current accounting period are $400,000 and 10,000 hours, respectively. Information about the two products follows. L24 Estimated production volume Direct materials per unit Direct labor per unit 3 hours at $8 S hours at $8 L23 1000 S30 1.400 $19 24 40 The company has seen a significant decline in profit and believes that incorrect and "outdated" calculations of product cost are a major contributor to the problem.
