Answer:
38880
Step-by-step explanation:
Budgeted sales -870 boxes
Each box requires 44 pounds of clay
Opening inventory of clay = 3900 pounds
Closing inventory of clay = 4500 pounds
Clay mix cost - $0.40
Labor rate = $12/hr
Monthly purchase = budgeted sales + closing inventory - opening inventory
(870*44) + 3900 - 4500
38280 +4500 - 3900 = 38,880
