Direct materials 3feet $5 per foot $15
Direct labor ? hours ? per hour ?

During March, the company purchased direct materials at a cost of $59,040, all of which were used in the production of 3,000 units of product. In addition, 4,600 hours of direct labor time were worked on the product during the month. The cost of this labor time was $34,500. The following variances have been computed for the month:

Materials quantity variance $4,200 U
Labor spending variance $3,900 U
Labor efficiency variance $680 U

Required:
1. For direct materials:
a. Compute the actual cost per foot for materials for March. (Round your answer to 2 decimal places.)
b. Compute the price variance and the spending variance. (Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i. e., zero variance))

2. For direct labor:
a. Compute the standard direct labor rate per hour. (Do not round intermediate calculations. Round your final answer to 2 decimal places.)
b. Compute the standard hours allowed for the month’s production.
c. Compute the standard hours allowed per unit of product. (Round your answer to 1 decimal place.)
