3. You have noticed that when a business sells products to another, the resulting transactions affect the books of both the seller and the purchaser. Assume that the computer manufacturer HP is the seller and Costco is the purchaser. Journalize the following merchandising operations related transactions for BOTH the companies. Use seller and purchaser identities in your headings.

a. HP sold 1,000 computers to Costco for $500,000 on terms of 3/10, n/30. The computers had an inventory cost to HP of $300,000.

b. Costco returned 200 of those computers, for which the total purchase price was $100,000 (HPs cost was $60,000).

c. Costco paid HP for the remaining computers within the discount period.

d. HP paid the $1,000 transportation cost on the shipment.
