The question of beginning inventory for Midnight Supplies and data, i have attempted this problem and have not come up with the correct answer for the Weighted Average Cost of Goods sold? Every time I put the answer into Cengage`s box for the COGS it does not have a green check mark, only a pink box indicating that the answer is wrong. Can you try to resolve the answer because I cannot find a solution to resolve this answer, all the FIFO, and LIFO are correct except for the Weighted Average COGS which is a minus to the Gross Profit.
