Explanation:
The cash balance as at the end of December 31 2020 is the net cash provided by operating activities, less net cash used by investing activities plus net cash provided by financing activities plus the beginning cash balance as at January 1, 2020
Net cash provided by operating activities = $569,000
Net cash used by investing activities = $988,000
Net cash provided by financing activities = $595,000
Beginning cash balance = $331,000
Closing cash balance = $569,000 - $988,000 + $595,000 + $331,000
Closing cash balance = $507,000
