Tiago makes three models of camera lens. Its product mix and contribution margin per unit follow:

	Percentage of Unit sales		Contribution Margin per unit
Lens A	32	%	$	42
Lens B	34			34
Lens C	34			47

Suppose the product mix has shifted to 37/32/31. Required: 1. Determine the new weighted-average contribution margin per unit. (Round your intermediate calculation to 2 decimal places. Round your answer to 2 decimal places.)

2. Determine the number of units of each product that Tiago must sell to break even if fixed costs are $191,000

3. Determine how many units of each product must be sold to generate a profit of $68,000
