a) No of units produced = 409500/45 = 9100 Units
b) Material quantity variance = (SQ-AQ)SP
-9300 = (9100*9*5-5X)
5X = 418800
X(actual pounds purchased) = 418800/5 = 83760 Pounds
c) Material price variance = (SP-AP)AQ
4188 = (5*83760-83760X)
83760X = 418800-4188
X(actual price) = 4.95
d) Labor efficiency variance = (SH-AH)SR
-6200 = (9100*.70*10-10X)
10X = 63700+6200
X(Actual hour) = 6990 Hour
e) Labor rate variance = (SR-AR)AH
-4893 = (10*6990-6990X)
6990X = 69900+4893
X(Actual rate) = 10.70
