Tower Company planned to produce 3,000 units of its single product, Titactium, during November. The standards for one unit of Titactium specify six grams of materials at $0.30 per gram. Actual production in November was 3,100 units of Titactium. There was a favourable materials price variance of $380 and an unfavourable materials quantity variance of $120. Based on these variances, one could conclude that: Select one: a. more materials were purchased than were used. O b. the actual usage of materials was less than the standard allowed. c. the actual cost per gram for materials was less than the standard cost per gram. d. more materials were used than were purchased. The fixed overhead volume variance is due to: Select one: a. inefficient or efficient use of overhead resources, 0 b. inefficient or efficient use of whatever the denominator activity is c. a difference between the denominator activity and the standard hours allowed for the actual output of the period. 0 d. a shift in the amdant of hours required to produce the actual output
