can you please explain how to solve these? what equations to use?

"Wonderful! Not only did our salespeople do a good job in meeting the sales budget this year, but our production people did a good job in controlling costs as well," said Kim Clark, president of Martell Company. Our $18,300 overall manufacturing cost variance is only 1.2% of the $1,525,000 standard cost of products made during the year. That's well within the 3% parameter set by management for acceptable variances. It looks like everyone will be in line for a bonus this year. The company produces and sells a single product. The standard cost card for the product follows: Inputs Direct materials Direct labor Variable overhead Fixed overhead (1) Standard Quantity or Hours 2 feet 1.4 hours 1.4 hours 1.4 hours (2) Standard Pride on Rate 8.45 per foot 16 per hour 2.50 per houm 6 per hour 15 $ $ $ Standard dost (1) X (2) $ 16.90 22.40 3.50 8.40 $ 51.20 Total standard cost per unit The following additional information is available for the year just completed: a. The company manufactured 30,000 units of product during the year. b. A total of 64,000 feet of material was purchased during the year at a cost of $8.55 per foot. All of this material was used to manufacture the 30,000 units produced. There were no beginning or ending inventories for the year. C. The company worked 43,500 direct labor-hours during the year at a direct labor cost of $15.80 per hour. d. Overhead is applied to products on the basis of standard direct labor-hours. Data relating to manufacturing overhead costs follow Check my work Denominator activity level (direct labor-hours) Budgeted fixed overhead costs Actual variable overhead costs incurred Actual fixed overhead costs incurred 35,000 $ 210,000 $ 108,000 $ 211,800 Required: 1. Compute the materials price and quantity variances for the year. 2. Compute the labor rate and efficiency variances for the year. 3. For manufacturing overhead compute: a. The variable overhead rate and efficiency variances for the year. b. The fixed overhead budget and volume variances for the year. (For all requirements, indicate the effect of each variance by selecting "Fi for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.) 1 Materials price variance Materials quantity variance 2. Labor rate variance Labor efficiency variance 3a.
