The computation is shown below:
(a) Standard direct materials price per pound of raw materials is
= Purchase price + freight in + receiving and handling
= $3 + $0.50 + $0.20
= $3.70
(b) Standard direct materials quantity per gallon is
= Required material + allowance for waste and spoilage
= 3.50 pounds + 0.80 pounds
= 4.30 pounds
(c) Total Standard direct materials cost per gallon is
= Standard direct materials price per pound of raw materials × Standard direct materials quantity per gallon
= $3.70 × 4.30 pounds
= $15.91
We simply applied the above formulas
