Answer:
$78320
Step-by-step explanation:
Given That:
Opening Balance of Accounts Receivable as on Dec 1, 2017 = $20500
Credit Sales Made during the month = $54900
Collection from Accounts Receivables during the month = $ 43920
Closing Balance of Accounts Receivables as on Dec 31, 2017 = Credit Sales made during the month + Amount collected from Accounts receivables - Opening balance of accounts receivables
Closing Balance = 54900 + 43920 - 20500
Closing Balance = $78320
