Answer: $53,600
Explanation:
Credit sales increase the balance on Accounts Receivables because they represent that people owe the business.
It is therefore included in the formula for calculating the ending balance of Accounts Receivables:
Ending accounts receivables = Beginning accounts receivable + Credit sales in May - Customer payments during May
19,000 = 24,600 + Credit Sales in May - 59,200
Credit Sales in May = 19,000 + 59,200 - 24,600
= $53,600
