Madzinga's Draperies manufactures curtains. Curtain #4571 requires the following: Direct material standard 10 square yards at $5 per yard Direct labor standard 5 hours at $10 per hour During the second quarter, the company purchased 20,400 square yards at a cost of $99,960 and used 19,800 square yards to produce 1,800 Curtain #45715. Direct labor totaled 9,120 hours for $95,760. a. Compute the material price and quantity variances. Note: Do not use a negative sign with your answers. Material price variance $ 0 Favorable 0 0 Material quantity variance $ 0 Unfavorable b. Prepare the journal entries for the purchase and use of direct material. Note: Round amounts to the nearest whole dollar. Note: Record any multiple debits or any multiple credits in alphabetical order by account name.

Recently, company facilities were automated, and the accounting system was revised to show only two cost categories: direct material and conversion. Estimated variable and fixed conversion costs for the current month were $306,000 and $136,800, respectively. Expected output for the current month was 9,000 rotors, and the estimated number of machine hours was 18,000. During July, the firm actually used 16,200 machine hours to make 8,640 rotors while incurring $410,400 of conversion costs. Of this amount, $270,000 was variable cost. Using the four-variance approach, compute the variances for conversion costs. Note: Do not use negative signs with your answers. Fixed Conv. Spending Variance Actual Fixed Conv. - Budgeted Fixed Conv. = Spending Variance $ 0 - $ O = 0 Fixed Conv. Volume Variance Budgeted Fixed Conv. - Applied Fixed Conv. = Volume Variance $ 0 - $ 0 = $ 0 Variable Conv. Spending Variance Actual Var. Conv. - Budgeted Var. Conv. = Spending Variance $ 0 - $ 0 = $ 0 Variable Conv. Efficiency Variance Budgeted Var. Conv. - Applied Var. Conv. = Efficiency Variance $ 0 - $ 0 = $ 0 Please answer all parts of the question.Calista & Lane, CPAs, set the following standard for its inventory audit of Triumph Co.: 770 hours at an average hourly rate of $250.
