Requirement 10. Say the company adds a second size of SD card (512GB in addition to 256GB). A 512GB SD card will sell for $45 and have variable cost per unit of $20 per unit. The expected sales mix is three of the 256GB SD cards for every one of the 512GB SD cards. Given this sales mix, how many of each type of SD card will the company need to sell to reach its target monthly profit of $260,000? Is this volume higher or lower than previously needed (in Question 5) to achieve the same target profit? Why? Begin by computing the weighted-average contribution margin per unit.
