Tiago makes three models of camera lens. Its product mix and contribution margin per unit follow: Suppose the product mix has shifted to 41%/30%/29%. Required: 1. Determine the new weighted-average contribution margin per unit. 2. Determine the number of units of each product that Tiago must sell to break even if fixed costs are $194,000. Suppose the product mix has shifted to 41%/30%/29%. 3. Determine how many units of each product must be sold to generate a profit of $66,000 if fixed costs are $194,000. Suppose the product mix has shifted to 41%/30%/29%. Complete this question by entering your answers in the tatis below. Determine the new weighted-average contribution margin per unit. Note: Round your intermediate calculations and final answer to 2 decimal places, Determine the number of units of each product that Tiago must sell to break even if fixed costs are $194,000. Suppose the product mix has shifted to 41%/30%/29%. Note: Do not round your intermediate calculations. Round up your final answer to the nearest whole unit.
