In its first month of operations, Ayayai Company made three purchases of merchandise in the following sequence: $(1)180$ units at $$4,(2)280$ units at $$5,$ and $(3)380$ units at $$8.$ Assuming there are $220$ units on hand, compute the cost of the ending inventory under $(1)$ the FIFO method and $(2)$ the LIFO method. Ayayai uses a periodic inventory system.
