Heels Ltd produces two brands of shoe. The "Everyday" sell for 150 per pair, and the "Occasion" sells for 350 per pair. They mark up variable costs by 50% and then add an additional "fashion premium" mark up of 80 to a pair of Occasion shoes. They forecast they will sell 9,750 pairs of Everydays a year, and 3,000 pairs of Occasions. They spend 4 labour hours to produce a pair of Everyday and 6 labour hours to produce a pair of Occasion. After 8 months of the year they are asked to produce a one-off batch of "Hybrids" by year end. The batch will be for 2,000 pairs of shoes and they will take 5 hours to make per pair, and total variable cost for the Hybrid will be 30% greater than for an Everyday. Heels Ltd is targeting annual contribution of 540,000, has fixed costs of 405,000, and have a maximum of 5,000 labour hours available per month. a. What is the current contribution per unit of an Everyday and an Occasion? (2 marks) b. How much contribution will have been earned after 8 months? (2 marks) c. Given Heels commit to fulfilling the order for Hybrids, and given the monthly labour hours constraint, what is the optimal number of Everydays and Occasions that can be produced in the last 4 months of the year? (3 marks) d. What is the minimum price they can charge per pair for the Hybrids whilst definitely filling that order in full and meeting the annual profit target? (4 marks) e. If the price of a hybrid is set at 170 and the order for Hybrids can only be completed in full or not at all, what is the optimal total contribution for the year? (4 marks)
