Tiago makes three models of camera lens. Its product mix and contribution margin per unit follow: Suppose the product mix has shifted to 47%/27%/26%. 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 $189,000. Suppose the product mix has shifted to 47%/27%/26% 3. Determine how many units of each product must be sold to generate a profit of $64,000 if fixed costs are $189,000.
