Answer:
Material A = 234,000 lbs.
Material B = 39,000 lbs.
Explanation:
First we must determine how many units we have to manufacture:
expected sales + ending inventory - beginning inventory = 76,000 + 10,500 - 8,500 = 78,000 units to be manufactured
now we calculate the amount of direct materials used:
Material A: 78,000 units x 3 lbs. per unit = 234,000 lbs.
Material B: 78,000 units x 1/2 lb. per unit = 39,000 lbs.
