Answer:
A. Current Ratio 3.66	times
B. Inventory turnover 4.47	times
C. Accounts receivable turnover 14.57	times
D. Earnings per share $7.72
E.Profit margin ratio 28.56%	
F.Return on assets 81.82% 
Explanation:
A. Computation for Current Ratio
Using this formula
Current Ratio=Total Current Assets/Total Current Liabilities
Where,	
Total Current Assets
Cash	$45,100	
Receivables	$96,200	
Inventory	$169,300	
Prepaid Insurance	$8,100	
Total Current Assets $318,700	
Total Current Liabilities
Notes payable (short-term)	$50,300	
Accounts Payable	$31,700	
Accrued liabilities	$5,100	
Total Current Liabilities $87,100	
Let plug in the formula
Current Ratio=$318,700/$87,100
Current Ratio=3.66	times
Therefore Current Ratio is 3.66	times
B.Calculation to determine Inventory turnover
Using this formula
Inventory turnover=Cost of Goods Sold/Average Inventory 
Where,
Cost of Goods Sold $830,100	
Average Inventory =[($201,900 + $169,300)/2] Average Inventory=	$185,600	
Let plug in the formula
Inventory turnover=$830,100/$185,600
Inventory turnover =	4.47	times
Therefore Inventory turnover is 4.47	times
C. Calculation to determine the Accounts receivable turnover
Using this formula 
Accounts receivable turnover=Net credit sales .
/Ending Receivables
Let plug in the formula
Accounts receivable turnover=$1,401,400/$96,200	
Accounts receivable turnover =	14.57	times
Therefore Accounts receivable turnover =is 14.57	times
D. Calculation to determine Earnings per share: 
Using this formula
Earnings per share=Earnings available to the common shareholders/Weighted average number of common shares
Where,
Earnings available to the common shareholders =
Net Income	$400,200	
Less: Preferred dividends	$0	
$400,200	
Weighted average number of common shares = ($259,100/$5)	51,820	
Let plug in the formula
Earnings per share =$400,200/51,820
Earnings per share =	$7.72	
Therefore Earnings per share is $7.72	
E. Calculation to determine Profit margin ratio: 
Net Income (a)	$400,200	
Net credit sales (b)	$1,401,400	
Profit margin ratio (a/b*100)	28.56%	
Therefore Profit margin ratio is	28.56%
F. Calculation to determine Return on assets on December 31, 2020: 
Net Income (a)	$400,200	
Total assets (b)	$489,100	
Return on assets (a/b*100) 81.82%
Therefore Return on assets is 81.82%
