Answer:
Option c) Debit Cash ($490); Debit Allowance for sales discounts ($10); Credit Accounts receivable ($500)
Explanation:
When the company anticipate the allowance for prompt payment discounts it makes the next entry in the accounting:
discounts for prompt payment (Debit) $10 -
Allowance for sales discounts (Credit) $10
When the discount was executed the company doesn't need to entry the discounts for prompt payment because it was recognize before.
So, the company has to make the next entry in the accounting system:
Debit - Cash ($490)
Debit - Allowance for sales discounts ($10);
Credit - Accounts receivable ($500)
With this entry we recognize the total balance in the Accounts Receivable and compensate the Allowance for sales discounts registered before.
