Requirement 3. Calculate the total direct materials mix and yield variances Begin by selecting the formula and entering the amounts to calculate the total direct materials mix variance. Identify each variance as either factorable (F) or unfavorable (U). direct materials input, ADM mix % = Actual direct materials input mix percentage ATQ inputs used= Actual total quantity of all direct materials inputs used. BS of DM input = B Budgeted total quantity of all direct materials inputs allowed for actual output, Mix var. = Direct materials mix variance for each input.) Mix var Peanuts 111 Cran.
