Calculate Net Fixed assets- given, longterm-debt to total assets ratio is 0.70, current ratio of 1.20, current liabilities are $850, sales are $4,310, profit margin is 9.5% and ROE is 21.5%.

It would have helped if you had posted your solution to the problem to be able to guide you, However, as a guidance follow these steps:
1. Calculate net income = Sales x profit margin
2. Divide net income by ROE% to get equity
3. Since equity is 0.30 of the total assets, find total assets by dividing equity with that ratio
4. Calculate current assets by using current liabilities x current ratio
5. Deduct current assets from total assets to get net fixed assets
