Toys R Fun purchased $4,000 of merchandise for resale and paid immediately. To record this transaction, Toys R Fun's accountant would debit the account and credit the account.

Debit Merchandise Inventory and Credit Cash

Explanation:

You made a purchase of merchandise that was paid now so that would increase your merchandise inventory.  Cash is credited because you paid them cash and you cash account decreased.

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."
