Accounts Payable	$	72,000		$	43,500

 

What is the amount of cash received from customers for Hope Company in 2021?

Answer 1

One of the easiest equations I have found that works for looking at changes over years is:

Beginning Balance + Activity - Ending Balance = Changes

For this example:

$57,000 + $184,000 - $25,000 = $216,000 Cash Collection
