Along with the demand of more books, the movable printing technology was accordingly invented, which is a significant contribution made by china to the human beings. Inexpensive printed books became widely availabe in China during Song dynasty.
Tip. 1  You may also calculate the overhead rate based on direct labor hours. 2  Divide the overhead costs by the direct labor hours over the same measurement period. 3  In the example, the overhead rate is $20 for each direct labor hour ($2,000/100).ou may estimate the costs using historical data and then adjust for inflation. For example, if your plant uses an average 100 direct labor hours per day at $15 an hour and you expect a two percent inflation rate in the upcoming year, your direct labor costs are $1,530 (1.02 x 100 x $15) per day. Step 2.
Problem 3: Labor Variance Analysis: The processing of a product requires a standard of 0.8 direct labor hours per unit for Operation 4-802 at a standard wage rate of $6.75 per hour. The 2,000 units actually required 1,580 direct labor hours at a cost of $6.90 per hour.Required: Calculate: labor rate variance or Labor price variance.roblem 3: Labor Variance Analysis: The processing of a product requires a standard of 0.8 direct labor hours per unit for Operation 4-802 at a standard wage rate of $6.75 per hour.
