Use both Weighted Average Costs and FIFO Inventory valuations.

Question $1$:

A company purchased $200$ units at $$5$ per unit, followed by $150$ units at $$6$ per

unit. They sold $100$ units, and later, $20$ units were returned.

Calculate the initial weighted average cost per unit before the sale.

Determine the cost of goods sold for the $100$ units sold.

Adjust the inventory and weighted average cost after the $20$ units are

returned.

Calculate the value of the ending inventory after the return.

Question $2$:

A company makes the following purchases throughout the year:

Q$1$: $300$ units at $$5$ per unit

Q$2$: $200$ units at $$4$ per unit

Q$3$: $500$ units at $$6$ per unit

Q$4$: $400$ units at $$7$ per unit

They sold $250$ units in each quarter.

Calculate the weighted average cost per unit after each quarter.

Determine the total cost of goods sold for the year.

Calculate the value of the ending inventory at the end of the year.

Question $3$:

A company has the following transactions during a half$-$year period:

Purchase: $200$ units at $$5$ per unit in January

Sale: $150$ units in March

Purchase: $300$ units at $$6$ per unit in April

Sale: $200$ units in June

Calculate the weighted average cost per unit after each purchase.

Determine the cost of goods sold for each sale.

Calculate the value of the ending inventory at the end of June.
