Please help me find moving average cost and LIFO under perpetual inventory system.

Ehrhart Appliance uses a perpetual inventory system. For its flat-screen television sets, the January 1 inventory was 5 sets at $610 each. On January 10, Earhart purchased 8 units at $680 each. The company sold 3 units on January 8 and 5 units on January 15. Your answer is correct. Compute the ending inventory under FIFO. Your answer is incorrect. Compute the ending inventory under LIFO. Compute the ending inventory under moving-average cost
