A machine distributor sells two models, basic and deluxe. The following information relates to its master budget.

	Basic			Deluxe
Sales (units)		11,200			2,800
Sales price per unit	$	9,600		$	13,600
Variable costs per unit	$	8,960		$	10,200

Actual sales were 10,200 basic models and 3,600 deluxe models. The actual sales prices were the same as the budgeted sales prices for both models. Is the sales mix variance for the basic model favorable or unfavorable?
