Answer:
$345,000
Explanation:
Since Halka Company uses a maturity matching approach, it must match its short term working capital with its short term debts, and its long term working capital with its long term debts. Halka's assets should be compensated with a corresponding debt instrument of similar maturity.
Since Halka's assets vary form $345,000 to $410,000, its long term debt plus equity should match at least $345,000.
