Please help me solve these equations. Please show your work so that I can learn.

Gross profit margin = 70% Inventory turnover ratio = 5 times Sales = $4,000 Net profit margin = 5% Average collection period = 45 days Return on equity = 50% Return on assets = 20% Cash = $75 Current ratio = 2.50 times Accounts payable days = 30 days

Note: Of total sales, 80 percent are on credit and the remainder are cash sales. Assume a 360-day year.

Cash	__________		Notes payable	__________
Accounts receivable	__________		Accounts payable	__________
Inventory	__________		Long-term debt	__________
Net fixed assets	__________		Equity	__________
Total assets	__________		Total liab. & equity	__________
