Answer:
Change in liabilities = $33,300
Explanation
<em>According to the accounting equation, assets is equal to liabilities + equity. And this equation can be re-written as:</em>
Liabilities = assets - equity
Liabilities at the end of the period = assets at the end - equity at the end
Assets at the end= 117,000 + 56,700= 173,700
Equity at the end = 88,500 + 23,400 = 111,900
Liabilities at the end = 173,700 - 111,900=61800
Change in liabilities = Liabilities at the end - Liabilities at the beginning
Change in liabilities = 61,800 - 28,500= $33,300
