In addition, 4,900 hours direct labor time were worked on the product during the month. The cost of this labor time was $39,200. The following variances have been computed for the month: | | | Materials quantity variance | $ | 3,000 | U | Labor spending variance | $ | 3,200 | U | Labor efficiency variance | $ | 750 | U | | 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)) | | | | | | | Price variance | | | Spending variance | | | | | |
