In its first month of operations, Vaughn Company made three purchases of merchandise in the following sequence: (1) 330 units at $ 8, (2) 450 units at $ 9, and (3) 230 units at $ 10. Assuming there are 410 units on hand, compute the cost of the ending inventory under the (a) FIFO method and (b) LIFO method. Vaughn uses a periodic inventory system.
