Working capital cannot be calculated without current liabilities Steps:

• Calculate current assets: total assets minus non-current assets = $160,000 -$120,000 = $40,000.
• Non-current liabilities are $45,000, but current liabilities are not given.
• Working capital = current assets - current liabilities; current liabilities require total liabilities or equity, which are missing.
• Not enough information to determine working capital.

Why A is correct:

• Not applicable; insufficient data prevents selecting any option.

Why the others are wrong:

• B: No basis for $23,000 without current liabilities.
• C: No basis for $7,000 without current liabilities.
• D: No basis for $15,000 without current liabilities.

Final answer: Not enough information.
