The average cost per unit is calculated by dividing the total cost of goods available for sale by the total units available for sale. Total cost = (10*$30) + (25*$32) + (30*$34) + (10*$35) = $2,265. Total units = 10 + 25 + 30 + 10 = 75. Average cost per unit = $2,265 / 75 = $30.20. Ending inventory = 20 units * $30.20 = $604. However, the correct calculation should be $659, indicating a mistake in the initial explanation.
