Answer:Balance of the mortgage payable after first installment = $142,000
Step-by-step explanation:
Interest Expense of First Installment = Principal x Interest Rate
= $160,000 X 15% = $24,000
Principle amount of the installment=Total annual installment−Interest of the first installment
=$42,278 −$24,000 =$18,278
Balance of the mortgage payable= Opening mortgage payable balance
−Principle amount of the first installment
=$160,000 - $18,278
=$141,722 rounded up to $142,000
