Need help answering these questions based on my given data

You will need to figure the Number of Units Available and Cost of Goods Available. Then, figure out the value of Ending Inventory given the three separate cost flow assumptions. Do include correct use of commas in your answers. Do not include dollar signs. Round all amounts to the nearest whole cent for Weighted Average.

Question 2 What is the Cost of Goods Available? Question 3 How many units will be in Ending Inventory? What is value of Ending Inventory using the Weighted Average cost flow assumption? Question 5 What is value of Ending Inventory using the FIFO cost flow assumption? Question 6 What is the value of Ending Inventory using the LIFO cost flow assumption
