(Click the icon to view the data.) Read the requirements. Requirement 1. Calculate the total variable cost per unit for each firm in the trade association. Compute the percent of total for the material, labor, and variable overhead components. (Round all cost amounts to the nearest cent. Round the percentages to two decimal places. Due to rounding the total of the percentages may not equal 100%. Firm A - Firm X B Firm C i Firm D Data Table Direct materials Direct labor Variable overhead Total Requirement 2. Using the trade association's industry benchmark, calculate direct materials and direct manufacturing labor price and efficiency variances for the four firms. Calculate the percent over Before calculating the variances, determine the formula you will use to calculate the price variance of each firm.

Calculate the percent over standard for each firm and each variance. Label each variance as favorable (F) or unfavorable (U). (Round all amounts to two decimal places. For amounts with a $0 balance, make sure to enter "0" in the appropriate field. If the variance is zero, do not select a label. Use parentheses or a minus sign for percentages under standard.
