Ramort Company reports the following cost data for its single product. The company regularly sells 20,000 units of its product at a price of $60 per unit. If Ramort doubles its production to 40,000 units while sales remain at the current 20,000-unit level, by how much would the company's contribution margin increase or decrease under variable costing?

Direct materials	$	10	per unit
Direct labor	$	12	per unit
Overhead costs for the year
Variable overhead	$	3	per unit
Fixed overhead per year	$	40,000
Selling and adminstrative costs for the year
Variable	$	2	per unit
Fixed	$	65,200
Normal production level (in units)		20,000	units

Would the income be different if using variable costing instead of absorption costing?
