Hello I have a question to double check a completed income statement

Hampshire Company
Variable Costing Income Statement
	Units	$
Sales	60,000	$12.50		$750,000.00
Variable Cost of Goods Sold:
Beginning Inventory		0	$0
Direct Materials	80,000	$3.00	$240,000.00
Direct Labor	80,000	$1.50	$120,000.00
Manufacturing Overhead	80,000	$0.40	$32,000.00
Total Variable Costs			$392,000.00
Cost of Good Available for Sale			$392,000.00
Deduct Ending Inventory	20,000	$4.90	$98,000.00
Variable Costs of Goods Sold				$294,000.00
Variable Selling Costs	60,000	$1.10	$66,000.00	$66,000.00
Contribution Margin				$390,000.00
Fixed Costs:
Fixed Manufacturing Costs				$216,000
Fixed Administrative Costs				$79,525
Operating Income				$94,475.00

I made bold the ending inventory. Is that correct? Is looks like the number 4.90 was just the variable costs but wouldnt it be 20,000 times 12.50 (the per unit cost) instead of the variable unit cost of 4.90? Is the formula for ending inventory amount of units left 20,000 times cost per unit 12.50? or is it times the 4.90?

Also for the variable selling costs I see they got 60,000 and 1.10 per unit. where does that come from?

Any help would be very appreicated thank you!!!!!
