What am I doing wrong?
Units sold 9000 @ $200 p/unit
Direct materials = 5400.00 (60 x 900)
Direct labor= $2700.00 (30 x 900)
Variable Manufacturing = 10 (Should I multiply this by 9000?)
Variable selling and adm= 20 (Should I multiply this by 9000?)

As it appears from the question, you have used 9000 as units sold and have calculated direct materials and direct labor costs for 900 units. Again, for variable manufacturing, selling administration expenses you are using 9000 units. Please recheck your figures.
