I was able to do the formula for the 1st Raw Materials section, I keep getting wrong answers for the rest. Any help would be appreciated with steps.

Thank you!!!

The Devon Motor Company produces automobiles. On April ist the company had no beginning inventories and it purchased 5,630 batteries at a cost of $60 per battery. It withdrew 5,200 batteries from the storeroom during the month. Of these, 100 were used to replace batteries in cars being used by the company's traveling sales staff. The remaining 5,100 batteries withdrawn from the storeroom were placed in cars being produced by the company.
