Materials Variances Assume that Pearle Vision uses standard costs to control the materials in its made-to-order sunglasses. The standards call for 2 ounces of material for each pair of lenses. The standard cost per ounce of material is $16.50. During July, the Santa Clara location produced 5,200 pairs of sunglasses and used 9,900 ounces of materials. The cost of the materials during July was $17.25 per ounce, and there were no beginning or ending inventories. Required a. Determine the flexible budget materials cost for the completion of the 5,200 pairs of glasses. $ b. Determine the actual materials cost incurred for the completion of the 5,200 pairs of glasses and compute the total materials variance. $ actual materials cost $ total materials variance c. How much of the total variance was related to the price paid to purchase the materials? $ d. How much of the difference between the answers to requirements (a) and (b) was related to the quantity of materials used? (Hint: Compute materials quantity variance.) $
