Coca-Cola Company produces three types of beverages: Coke, Sprite, and Fanta. The selling price and variable cost per unit for each product are as follows:

Product	Selling Price per Unit	Variable Cost per Unit
Coke	$1.50	$0.60
Sprite	$1.20	$0.50
Fanta	$1.00	$0.40

If the sales mix is 40% Coke, 30% Sprite, and 30% Fanta, calculate the weighted average selling price and contribution margin per unit.
