EA 1.

LO 8.1Moisha is developing material standards for her company. The operations manager wants grade A widgets because they are the easiest to work with and are the quality the customers want. Grade B will not work because customers do not want the lower grade, and it takes more time to assemble the product than with grade A materials. Moisha calls several suppliers to get prices for the widget. All are within $0.05 of each other. Since they will use millions of widgets, she decides that the $0.05 difference is important. The supplier who has the lowest price is known for delivering late and low-quality materials. Moisha decides to use the supplier who is $0.02 more but delivers on time and at the right quality. This supplier charges $0.48 per widget. Each unit of product requires four widgets. What is the standard cost per unit for widgets?

LO 8.1Rene is working with the operations manager to determine what the standard labor cost is for a spice chest. He has watched the process from start to finish and taken detailed notes on what each employee does. The first employee selects and mills the wood, so it is smooth on all four sides. This takes the employee 1 hour for each chest. The next employee takes the wood and cuts it to the proper size. This takes 30 minutes. The next employee assembles and sands the chest. Assembly takes 2 hours. The chest then goes to the finishing department. It takes 1.5 hours to finish the chest. All employees are cross-trained so they are all paid the same amount per hour, $17.50.

  1. What are the standard hours per chest?
  2. What is the standard cost per chest for labor?

LO 8.1Use the information provided to create a standard cost card for production of one glove box switch. To make one switch it takes 16 feet of plastic-coated copper wire and 0.5 pounds of plastic material. The plastic material can usually be purchased for $20.00 per pound, and the wire costs $2.50 per foot. The labor necessary to assemble a switch consists of two types. The first type of labor is assembly, which takes 3.5 hours. These workers are paid $27.00 per hour. The second type of labor is finishing, which takes 2 hours. These workers are paid $29.00 per hour. Overhead is applied using labor hours. The variable overhead rate is $14.90 per labor hour. The fixed overhead rate is $15.60 per hour.

LO 8.2Sitka Industries uses a cost system that carries direct materials inventory at a standard cost. The controller has established these standards for one ladder (unit):

Standard Quantity times Standard Price equals Standard Cost. Direct materials, 3 pounds, $4.50 per pound, $13.50. Direct labor, 2.00 hours, $12.00 per hour, $24.00. Total cost, -, -, $37.50.

Sitka Industries made 3,000 ladders in July and used 8,800 pounds of material to make these units. Sitka Industries bought 15,500 pounds of material in the current period. There was a $250 unfavorable direct materials price variance.

  1. How much in total did Sitka pay for the 15,500 pounds?
  2. What is the direct materials quantity variance?
  3. What is the total direct material cost variance?
  4. What if 9,500 pounds were used to make these ladders, what would be the direct materials quantity variance?
  5. If there was a $340 favorable direct materials price variance, how much did Sitka pay for the 15,500 pounds of material?
EA 6.

LO 8.2Use the information provided to answer the questions.

Actual price paid per pound of material $14.50, Total standard pounds for units produced this period 12,500, Pounds of material used 13,250, Direct materials price variance favorable $4,637.50.

All material purchased was used in production.

  1. What is the standard price for materials?
  2. What is the direct materials quantity variance?
  3. What is the total direct materials cost variance?
  4. If the direct materials price variance was unfavorable, what would be the standard price?

LO 8.2Dog Bone Bakery, which bakes dog treats, makes a special biscuit for dogs. Each biscuit uses 0.75 cup of pure semolina flour. They buy 4,000 cups of flour at $0.55 per cup. They use 3,550 cups of flour to make 4,750 biscuits. The standard cost per cup of flour is $0.53.

  1. What are the direct materials price variance, the direct materials quantity variances, and the total direct materials cost variance?
  2. What is the standard cost per biscuit for the semolina flour?
