Question 4 In a meeting with Belinda, the customer who ordered job 42 from Question 3 was extremely pleased with the retro fridges and wants to order a new batch of 100 units. Belinda has accepted the new order and, for estimating the cost, multiplied the unit product cost you have calculated in Question 3(c) by 100. Required: Considering the information and numbers provided in Question 3, explain whether the cost estimated by Belinda for this new order of 100 units is accurate or not. Use numbers and calculations for supporting your answer and consider one factor that could undermine Belindas estimate. (Chapter 9, 10 marks)
