Using the information in P25-3A, compute the overhead controllable variance and the overhead volume variance.

Data From Problem 25-3A:

Hopkins Clothiers is a small company that manufactures tall-men’s suits. The company has used a standard cost accounting system. In May 2014, 11,200 suits were produced. The following standard and actual cost data applied to the month of May when normal capacity was 14,000 direct labor hours. All materials purchased were used.

                        

Overhead is applied on the basis of direct labor hours. At normal capacity, budgeted fixed overhead costs were $49,000, and budgeted variable overhead was $36,400.
Instructions
  (a) Compute the total, price, and quantity variances for (1) materials and (2) labor.
  (b) Compute the total overhead variance.
  (c) Which of the materials and labor variances should be investigated if management considers a variance of more than 4% from standard to be significant?
