Question 4 Liza owns a small bakery company catering for gourmet cakes and pastries. Her fixed cost is the cost of the mixer and baking tools, while variable costs include flour, sugar, eggs, and edible decorations. Contemplating business expansion, she is trying to decide how many commercial mixers to purchase and came out with the following projections: Quantity of Mixers Variable Cost (RM) Fixed Cost (RM) 15 orders 30 orders 45 orders 6,000 2,000 5,000 12,000 7,000 1,800 3,800 10,800 4 8,000 1,200 3,600 8,400 a) For each level of fixed cost, calculate Liza's total cost for producing 15, 30, and 45 orders per week. b) If Liza produces 15 orders per week, how many mixers should be purchased and the average total cost? Decide the same for 30 and 45 orders per week. Assume that Liza purchased three (3) mixers, expecting to produce 30 orders per week. c) Suppose that in the short run, business declines to 15 orders per week. What is Liza's average total cost per order in the short run? What if, instead, business boomed to 45 orders in the short run? d) What is Liza's long-run average total cost for 15 orders per week? Please explain why this short-run average total cost of producing 15 orders per week when the number of mixers is fixed at 3 is greater than her long-run total average cost of producing 15 orders per week. e) Draw Liza's long-run average total cost curve. Draw her short-run average total cost curve if she owns three (3) mixers
