T-Shirt City uses a periodic inventory system. During the first year of operations, the company made four purchases of a particular product. Each purchase was for 500 units and the prices paid were \($9\) per unit in the first purchase, \($10\) per unit in the second purchase, \($12\) per unit in the third purchase, and \($13\) per unit in the fourth purchase. At year-end, 650 of these units remained unsold. Compute the cost of goods sold under the FIFO method and LIFO method, respectively.

a. \(\$ 13,700\) (FIFO) and \(\$ 16,000\) (LIFO).

b. \(\$ 8,300\) (FIFO) and \(\$ 6,000\) (LIFO).

c. \(\$ 16,000\) (FIFO) and \(\$ 13,700\) (LIFO).

d. \(\$ 6,000\) (FIFO) and \(\$ 8,300\) (LIFO).
