Answer:
Total sales on account = $178,000
Explanation:
We have to determine Accounts receivable balance to determine how much sales on account during the year ended on December 31, 2019.
Cash collection from customers during the year (Accounts receivable decrease) = $147,000
Add: Accounts receivable increase due to sales on account = $31,000
Therefore, Total sales on account = $178,000
It means Pelkey company sold $178,000 on account while collecting $147,000 from customers during the year.
