Got really confused with these two questions, can someone exlain it to me?

Preble Company manufactures one product Its variable manufacturing overhead is applied to production based on direct labor-hours and its standard cost card per unit is as follows: Direct materials: 8 pounds at $10 per pound $ 80 Direct labor: 5 hours at $13 per hour 65 Variable overhead: 5 hours at $8 per hour 40 Total standard cost per unit $185 The planning budget for March was based on producing and selling 15,000 units. However, during March the company actually produced and sold 17,000 units and incurred the following costs: a. Purchased 170,000 pounds of raw materials at a cost of $8.00 per pound. All of this material was used in production. b. Direct laborers worked 64,000 hours at a rate of $14 per hour. c. Total variable manufacturing overhead for the month was $513,920. 6. If Preble had purchased 179,000 pounds of materials at $8.00 per pound and used 170,000 pounds in production, what would be the materials quantity variance for March? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable. and "None" for no effect (i.e., zero variance.). Input all amounts as positive values.) __ Dawson Toys, Ltd., produces a toy called the Maze. The company has recently established a standard cost system to help control costs and has established the following standards for the Maze toy: Direct materials: 7 microns per toy at $0.35 per micron Direct labor: 1.3 hours per toy at $6.80 per hour During July, the company produced 5,000 Maze toys. The toy's production data for the month are as follows: Direct materials: 73,000 microns were purchased at a cost of $0.33 per micron. 29.250 of these microns were still in inventory at the end ofthe month. Direct labor. 7,000 direct labor-hours were worked at a cost of $50,400. Required: 1. Compute the following variances for July: (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values. Do not round intermediate calculations. Round final answer to the nearest whole dollar amount.) a. The materials price and quantity variances. b. The labor rate and efciency variances. __ __ 13. Material price variance Material quantity variance 1b. Labor rate variance Labor efciency variance
