A conservatively financed firm would Multiple Choice O use long-term financing for all fixed assets and short-term financing for all other assets. O finance a portion of permanent assets and short-term assets with short-term debt. O use equity to finance fixed assets, use long-term debt to finance permanent assets, and use short-term debt to finance fluctuating current assets. O use long-term financing for three items: permanent current assets, fixed assets, and a portion of the short-term fluctuating assets. Then use short-term financing for all other short-term assets.The table belowr shows the inventory-sales ratio for manufacturing and Complete the table below. trade for a region over a period of 3 years.
