(a) Compute the total materials variance and the price and quantity variances. Total Materials Variance: AO X AP minus SO X SP = Variance Value X Value Value X Value = minus = ? F Materials price variance: AQ X AP minus AO X SP = Variance Value X Value Value X Value 11 ? minus ? ? F Materials quantity variance: AO X SP minus SO X SP = Variance Value X Value minus Value X Value - 2 minus - ? ? U
