Answer:
$154,700
Step-by-step explanation:
The computation of the change in amount is shown below
But before that first find out the ending capital balance which is 
= (Total assets - total liabilities) + (revenues - expenses) - drawings 
= ($300,000 - $208,000) + ($523,000 - $319,000) - $49,300
= $92,000 + $204,000 - $49,300
= $92,000 + $154,700
= $246,700
Now the change in capital balance is 
= Closing balance - opening balance 
= $246,700 - $92,000
= $154,700
